自1980年起,日本有关厂和公司就不断从我国购入小批量(几吨至数十吨)的稀土合金加以实验研究。这些研究已取得了进展,近年来相继发表了许多研究报告。特别是以汽车业为中心开展大量实验,取得明显效果。目前我国输入日本的稀土含金逐年增多,84年据统计已达1300吨左右,并且将继续增长。 Since 1980, Japan’s factories and companies have continuously experimented with the purchase of rare-earth alloys in small quantities (several tons to tens of tons) from our country. These studies have made progress and many studies have been published in recent years. In particular, the automotive industry as the center to conduct a large number of experiments, achieved significant results. At present, China’s import of rare earth gold in Japan increased year by year, according to statistics in 1984 has reached about 1,300 tons, and will continue to grow.
