在熔化铝的过程中,加NaF-NaCl熔体作熔剂,并向NaF-NaCl熔体中添加稀士氧化物(或其他稀土化合物),用铝还原RE_2O_3,可直接得到含铝的稀土合金或稀土中间合金。
In the process of melting aluminum, adding NaF-NaCl melt as flux, adding rare earth oxide (or other rare earth compound) to NaF-NaCl melt and reducing RE_2O_3 with aluminum to directly obtain aluminum-containing rare earth alloy or Rare earth intermediate alloy.
