日本1989年由苏联进口Y、Ce、La的氧化物和中间原料等,约400t(5.5亿日元)。日本开始生产彩电时,由苏联进口钇。中国掌握分离、提纯技术,是稀土金属的主要供应国,但问题是缺乏稳定性。从这一观点出发,苏联又能成为稀土金属的有力供给国。 钛镁最大的生产厂在乌斯特-卡敏诺哥尔斯克工厂,年产海绵钛4.6万吨,1989年向日本出口514t。苏联从1930年开始生产V_2O_5,在Kachkanar Japan in 1989 by the Soviet Union imported Y, Ce, La oxide and intermediate raw materials, etc., about 400t (550 million yen). When Japan began producing color TVs, yttrium was imported from the Soviet Union. China seize the separation, purification technology, is the main supplier of rare earth metals, but the problem is the lack of stability. From this point of view, the Soviet Union can become a powerful supplier of rare earth metals. The largest titanium magnesium production plant in the United States - Kaminoy Gorgsk factory, with an annual output of 46,000 tons of titanium sponge, in 1989 exports to Japan 514 t. The Soviet Union started producing V_2O_5 from 1930 at Kachkanar
