In 2017, the world's production of low-grade gallium was c. 315 tons—an increase of 15% from 2016. China, Japan, South Korea, Russia, and Ukraine were the leading producers, while Germany ceased primary production of gallium in 2016. The yield of high-purity gallium was ca. 180 tons, mostly originating from China, Japan, Slovakia, UK and U.S.

Following are responses from some companies to the announcement of curbs from Aug. 1 on Chinese gallium and germanium exports. * A spokesperson for the Semiconductor Equipment Association of Japan ...
The resulting production of 71 Ge was calculated in 2005 to be 79% of expected, [5] confirming an earlier (1998) estimate from one of the experiments on GALLEX (another gave results indistinguishable from 100%, similarly to the Cr experiment on SAGE). [6] [7] This discrepancy soon became known as the gallium anomaly.
China is a major producer of antimony, which is used in flame retardants, batteries, night-vision goggles and nuclear weapon production, according to a 2021 U.S. International Trade Commission report.
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits , monolithic microwave integrated circuits , infrared light-emitting diodes , laser diodes , solar cells and optical windows.
