法国和西德是世界上最大的镓生产国.中国、捷克、匈牙利、日本及挪威次之.近年来,由于砷化镓工业迅速发展,在其它国家也正在兴建新的镓精炼工厂.进入90年代砷化镓IC将投入正式生产,Nd-Fe-B系磁体和Sm-Co系磁体在性能上及价格上竞争激烈.Nd-Fe-B磁体添加镓,开发新的用途,提高竞争能力,对镓的需要量将有很大的增长.目前镓的消费以与光电子有关的需要量为主,年增长率估计为10～15%,最近在牙科用合金中添加镓的研究已取得成果,即将进入实用阶段;以镓取代汞齐的方法也取得进展,这可
France and West Germany are the largest producers of gallium in the world, followed by China, the Czech Republic, Hungary, Japan and Norway. In recent years, due to the rapid development of the gallium arsenide industry, new gallium refining plants are also being built in other countries. Nd-Fe-B magnet and Sm-Co magnet will be highly competitive in terms of performance and price. Gallium is added to Nd-Fe-B magnet to develop new use and improve competitiveness, The demand for gallium will have a great growth.Currently the consumption of gallium and photoelectron-related needs, the annual growth rate is estimated at 10 to 15%, the recent addition of gallium in dental alloys has been the achievement of research, It is about to enter the practical phase; progress has also been made in the replacement of amalgam with gallium, which may be
