It imposed controls over exports of germanium and gallium products last August. Spot prices of germanium ingot have jumped nearly a third in the past month to an all-time high of 13,250 yuan ...
The spot price of gallium metal reached 1,975 yuan ($269.95) per kg on Oct. 18, up 18% since the start of July and up 8% since Aug. 1, d Chinese gallium prices hit 7-month high as demand improves ...
The Pentagon holds a strategic stockpile for germanium but currently has no inventory reserves for gallium, a spokesperson said on Thursday, after China announced export restrictions on the two ...
Indium Corporation is a materials refiner, smelter, manufacturer, and supplier to the global electronics, semiconductor, thin-film, and thermal management markets.Products include solders and fluxes; brazes; thermal interface materials; sputtering targets; indium, gallium, germanium, and tin metals and inorganic compounds; and NanoFoil.
The target for the reaction was 50-57 tonnes of liquid gallium metal stored deep (2100 meters) underground at the Baksan Neutrino Observatory in the Caucasus Mountains in Russia. The laboratory containing the SAGE-experiment is called gallium-germanium neutrino telescope (GGNT) laboratory, GGNT being the name of the SAGE experimental apparatus.
Germanium is usually considered to be a metalloid rather than a metal. [124] Like carbon (as diamond) and silicon, it has a covalent tetrahedral crystalline structure (BCN 4). [125] Compounds in its preferred oxidation state of +4 are covalent. [126] Germanium forms an amphoteric oxide, GeO 2 [127] and anionic germanates, such as Mg 2 GeO 4.
China's export controls on some gallium and germanium products take effect on Tuesday with traders braced for a drop in international supply in August and September while exporters sort out newly ...
The parent isotope germanium-68 is the longest-lived (271 days) of the radioisotopes of germanium. It has been produced by several methods. [1] In the U.S., it is primarily produced in proton accelerators: At Los Alamos National Laboratory, it may be separated out as a product of proton capture, after proton irradiation of Nb-encapsulated gallium metal.
