| Abstract:Gallium is a kind of associated mineral, which is associated with aluminum, zinc and germanium, with no independent deposit. Gallium resources are abundant in China. As an important semiconductor material, gallium is widely used in radio communication, optical fiber communications, automotive radar, LED lighting, solar cells, and some other fields. Almost all gallium products are related to the current development of modern science and technology as well as to low carbon economy, green energy and environmental protection. With the growing of the gallium consumption and gallium application fields, the importance of gallium has aroused more and more attention in many countries. The authors made use of the sector analysis to predict global gallium metal demand in 2020, which is about 410~430 t. The problem of gallium industry in China was analyzed, and suggestions for increasing downstream gallium product competitiveness and protecting gallium metal production were proposed. |
