Rare earth magnets are used in wind turbines, electric vehicles and defence applications like laser guided missiles.Ĭhina has hinted at various times that it could crimp rare earths exports, including in recent years. Beijing said at the time the curbs were based on environmental concerns. In 2010, China restricted export quotas of rare earths to Japan following a territorial dispute between the countries, sending prices of rare earths soaring and Japan scrambling to find other sources of supply. Gallium at 99.99% purity in China was assessed at 1,775 yuan ($245) a kg on Monday, up 5.97% from the previous session and the highest since May 16, Shanghai Metal Exchange data on Refinitiv Eikon showed.Ĭhina's germanium ingot price was last at 9,150 yuan ($1,264) per kg on Monday, Shanghai Metal Exchange data on Refinitiv Eikon showed. "Zinc selenide and germanium glass substitute for germanium metal in infrared applications systems, but often at the expense of performance." HOW MUCH DO THEY COST? "Silicon can be a less-expensive substitute for germanium in certain electronic applications," according to USGS. In some applications, gallium in arsenide wafers can replaced by silicon or indium, according to USGS. They also produce less noise than silicon devices, especially at high operating frequencies, making them useful in radars and radio communication devices, satellites and LEDs, Wafer World says. Semiconductor wafers made with gallium arsenide rather than silicon can operate at higher frequencies and are heat resistant, according to U.S. It is also important for low-carbon technologies such as solar cells. The metal and its oxides are used in military applications like night-vision devices as well as satellite imagery sensors.

Germanium is key to fibre optic cables and also used in high-speed computer chips and plastics as well as infrared radiation. I was trying to use Refined Storage Importers/Exporters/Cables and a Refined Storage System but coming across an issue. The metals are used in high-speed computer chips and in the defence and renewable energy sectors. U.S.-based Indium Corporation also produces germanium, while Belgium's Umicore (UMI.BR) makes both germanium and gallium. After prices rallied in 20, Germany announced that it would restart primary gallium production.Ĭanada's Teck Resources (TECKb.TO) is the biggest germanium producer in North America, extracting the material from its Trail smelter in British Columbia. Germany and Kazakhstan also produced it in the past. Small amounts of primary gallium - around 10 metric tons in 2021 - are produced by Japan, Russia and South Korea, according to USGS, while additional amounts also come from recycled material.
