  • 20/04/23

UK-based cadmium zinc telluride (CZT) producer Kromek has signed multiple deals in the past month to develop CZT detectors for medical imaging, which is among the applications increasingly competing with solar for tellurium supply.

Kromek is one of only four companies globally that manufacture CZT, which it uses to produce imaging and detection equipment for civil nuclear applications, medical imaging and security screening.

Kromek has agreed to collaborate with sensor technology supplier Analogic on the development of next-generation CZT-based detectors for photon-counting computed tomography (PCCT) equipment in the medical imaging and security sectors.

PCCT detectors using CZT address limitations in conventional computed tomography (CT) detectors to increase spatial and energy resolution and reduce radiation doses, according to Kromek. This can improve image quality to enable the early detection of illnesses in medical imaging and identify dangerous items in security scans.

Kromek will integrate CZT sensors into Analogic's detector designs to optimise its detection systems. It will also provide the production capacity to support Analogic's PCCT demand.

Kromek has also signed an initial seven-year agreement this week with an unnamed tier 1 original equipment manufacturer (OEM) in the health technology sector to develop CZT-based detectors for use in advanced medical imaging scanners.

The agreement will transition to a longer commercial supply phase after a short development period, the companies said. The collaboration across development and supply will aim to facilitate the customer's progress in next-generation imaging-based technologies for precision diagnosis and therapy.

In March, Kromek signed repeat orders valued at a total of $1.1mn from three medical imaging customers in its key target market of single-photon emission computed tomography (SPECT).

Commercial demand for Kromek's CZT products for CT and SPECT applications has been increasing in the second half of its 2023 financial year ending in June, in addition to its long-term contracts, the company said.

The deals include a $300,000 order for detectors for niche SPECT applications, which is expected to be delivered in the company's 2023 financial year. A $563,000 order from an OEM for niche SPECT applications and a $205,000 order for niche medical imaging applications are from long-term customers, with delivery due to start before June and conclude in the first half of the 2024 financial year.

Kromek reported a 50pc year-on-year increase in revenue during its fiscal third quarter ending in March. The company expects strong revenue growth for the full financial year as it continues to trade in line with market expectations.

Tellurium market could tighten on new demand sources

Applications such as medical imaging and security scanning are increasingly using advanced semiconductor materials including CZT and gallium nitride, competing with their primary applications for supply.

The largest share of the world's tellurium output is used to produce cadmium-telluride (CdTe) solar panels — about 40pc — and the rapidly growing deployment of renewable energy capacity is increasing the industry's consumption. US-based First Solar, one of the world's largest CdTe panel manufacturers, has ambitious plans to ramp up its production capacity that would drive its tellurium consumption beyond the current level of global supply.

At the same time, demand from thermoelectric device manufacturers, which account for about 30pc of the market, and metallurgical applications, which account for about 15pc, is expected to rise in the coming years.

Bismuth telluride is used in thermoelectric devices for cooling and energy generation as well as sensors, and companies such as First Tellurium are developing new applications for tellurium in the sector. First Tellurium is also among the companies working to develop lithium tellurium batteries for electric vehicles.

Rising demand for nanostructured tellurium semiconductors and the rapid adoption of artificial intelligence are expected to add another new source of consumption.

As tellurium is largely produced as a by-product of copper mining, supply depends on demand for copper refining. China accounted for an estimated 53pc of global output of approximately 640t in 2022, with Russia, the second-largest producer, accounting for 12.5pc. Ongoing geopolitical tensions are giving further impetus to efforts to identify alternative sources of supply to meet the demand growth.

US Fed cuts rate by half point, signals more: Update

US Fed cuts rate by half point, signals more: Update

Adds chairman Powell comments, economic projections. Houston, 18 September (Argus) — The US Federal Reserve cut its target interest rate by 50 basis points today, the first rate cut since 2020, with policymakers signaling they expect to make another half-point worth of cuts by the end of 2024. The Fed's Federal Open Market Committee (FOMC) lowered the federal funds rate to 4.75-5pc from the prior range of 5.25-5.5pc, which was a 23-year high. The Fed had kept the target rate unchanged since July 2023 after hiking it for more than a year in the most intense rate-tightening campaign in four decades to quash inflation, which peaked at 9.1pc in mid-2022. "The committee has gained greater confidence that inflation is moving sustainably toward 2pc, and judges that the risks to achieving its employment and inflation goals are roughly in balance," the FOMC said in its statement after the two-day meeting. "Job gains have slowed, and the unemployment rate has moved up but remains low." In their latest economic projections, the Fed board and policymakers expect the target rate range will end 2024 near a midpoint of 4.4pc compared with an end of year midpoint of 5.1pc projected in June, which implies further cuts amounting to 50 basis points by the end of 2024. Policymakers also penciled in another 100 basis points of cuts over the course of 2025. "We're recalibrating policy down over time to a more neutral level and we're moving at the pace that we think is appropriate given developments in the economy," Fed chair Jerome Powell told a press conference after the meeting. "The economy can develop in a way that will cause us to go faster or slower. The US economy is in a good place and our decision today is designed to keep it there." The Fed's economic projections see core Personal Consumption Expenditures inflation — the Fed's favorite measure of inflation — ending 2024 at a median rate of 2.6pc, down from a prior forecast of 2.8pc. Policymakers see core PCE inflation falling to a median of 2.2pc by the end of next year. The outlook for the unemployment rate for the end of 2024 climbed to 4.4pc from 4pc penciled in at the June meeting. Policymakers expect gross domestic product (GDP) growth to end 2024 at an annual 2pc, slightly down from a prior 2.1pc projection. The latest policy meeting comes as the Consumer Price Index (CPI) eased to an annual 2.5pc in August , down from 2.9pc in July, the Labor Department reported on 11 September. Inflation had ticked up to 3.5pc in March from 3.1pc in January, prompting the Fed to turn more cautious about beginning its rate cuts. US job growth has recently slowed sharply, falling to an average 116,000 in the three months through August from 211,000 for the prior three months. The jobless rate rose to 4.3pc in July, the highest in three years, before edging down to 4.2pc in August.

Japan's Tokyo Steel cuts sales prices on weak demand

Shanghai, 18 September (Argus) — Japan's steel manufacturing firm Tokyo Steel said it will cut domestic steel product prices for October, marking the first full-scale price cut in over four years. The decision was driven by sluggish domestic demand and increased competition from cheaper imported steel products. Tokyo Steel will reduce prices across all product lines starting October, with steel coils and plates dropping by ¥15,000/t, shaped beams by ¥12,000/t, and tubes and deformed bars by ¥10,000/t. The company had maintained stable domestic steel prices for an extended period on the back of the steadier domestic demand and market conditions compared to the more volatile overseas market. The last price cut for deformed bars was in July 2023. Steel sales in Japan were weak during the third quarter, impacted by rising procurement costs for materials, a shortage of construction capacity, and an influx of cheaper steel products from China in the seaborne market, market participants said. A decline in profitability pushed Japanese mills to cut production costs. From 11 July to 14 September, domestic scrap prices at Tokyo Steel's Utsunomiya plant dropped by ¥12,500/t, or 23.8pc. Market sentiment in Japan remains bearish due to economic uncertainty and the strengthening of the Japanese yen. The upcoming adjustments in US monetary policy could add further volatility to exchange rates. "We may see more corrections in the Japanese domestic market," a trade source said.

July EU HRC imports show 175,000t pullback

London, 17 September (Argus) — EU hot-rolled coil (HRC) imports surpassed 1.5mn t in July — a record high — as importers for the first time faced a cap to the ‘other countries' safeguard quota, which led some to purchase back-up material from other sources. More importantly, official figures show that around 175,000t were pulled back from customs clearing, likely all in Italy, after the initial quota numbers were made available in early July from Egypt, Vietnam, Japan and Taiwan. This leftover amount will likely all be custom-cleared in October, in addition to material that has arrived since July, as market participants expect importers to clear all of their HRC to avoid the risk of retroactive duties, potentially applicable from December. Imports from Taiwan, India, Turkey and Japan in July all surpassed the 200,000t mark each, with total imports from those four origins close to 900,000t, a sharp year-on-year increase. Vietnam saw volumes drop ( see table ), while South Korean imports fell by 75pc on the year to 40,379t and Serbian imports were down by 10pc to 37,437t. Hot-dipped galvanised (HDG) imports were at a record high, topping 750,000t in July, with nearly 30pc of the total from Vietnam. There has been concern in the market that the EU might start an investigation on Vietnamese HDG, as volumes have been on the increase, while suppliers are regularly the lowest-priced in the market. Plate imports were also at a record high, as EU producers are preparing to file for an investigation on some origins. Meanwhile, the increase in imports and the drop in EU demand has led producers to seek export outlets, with EU HRC exports rising on the year and on the month in July to nearly 230,000t, with the bulk going to the UK, US and Turkey. Downstream product exports also increased.

US to impose 25pc tariffs on Chinese critical minerals

Houston, 13 September (Argus) — The US plans to impose 25pc tariffs on Chinese minerals including indium, tantalum, chromium, cobalt and tungsten, citing China's efforts to dominate global supply chains, according to the office of the US Trade Representative (USTR). The USTR determined not to exclude any critical minerals from the proposed Section 301 tariffs. The USTR said the concentration of mining and refining capacity of these minerals in China, as well as China's effort to dominate the global supply chains for these minerals, endangers US national security and clean energy goals. The Section 301 tariffs on indium, tantalum, chromium, cobalt, and tungsten will go into effect on 27 September. Tariffs on natural graphite and permanent magnets will go into effect on 1 January 2026. China is the leading producer and exporter of indium, producing an estimated 650t in 2023, about 66pc of the global total, according to the US Geological Survey (USGS). The US imported 219 metric tonnes (t) of unwrought indium in 2023, including 10t from China. So far in 2024 the country has imported 148t, of which 45t originated in China, according to data from the US Commerce Department. Indium is primarily used globally for its electric conductivity in a variety of screens including liquid crystal displays (LCDs) as well as fiber-optic cables and other technical components. US consumption is more focused around solders and specialty alloys. The US imports more tantalum powders, alloys, and metals from China than any other country. The US imported 321t of unwrought tantalum in 2023, including 132t from China and has imported 269t between January and July 2024, including 178t from China. Tantalum is primarily used in high-temperature alloys and capacitors. Although China accounted for only 3.3pc — 79t — of global 2023 mine production, the USGS estimated the country had a world-leading 240,000t of tantalum reserves. Chromium is primarily used in stainless and heat-resistant steels. China is the world's largest producer of ferrochromium and stainless steel. The US imported 103,034t of chromium ores and concentrates in 2023, including just 10t from China. Still, the US did import 9,302t of unwrought chrome metal from China so far in 2024, which accounted for 74pc of total volumes, and US reliance on China for the metal has increased since sanctions forced Russian supplies off the table. Although China does not mine a significant amount of cobalt, it is the world's leading cobalt refiner and consumer. The US imported 18t of cobalt ores and concentrates in 2023, including 11t from China, and imported 11t between January and July 2024, including 6t from China. The US imported 1.6mn contained kilograms (ckg) of tungsten carbides in 2023, including 906,000ckg from China and imported 1mn ckg between January and July 2024, including 491,000ckg from China. Tungsten is primarily used in carbide parts for construction, metalworking, mining, and drilling applications. Tungsten is also used in specialty steel fabrication as well as in electrodes, filaments, and wires for various electrical and electronic products.
