摘　　要：采用氟化氢铵氟化法制取氟化钪和选用高纯金属钙还原制取粗钪，再经真空蒸馏提纯可得相对纯度大于９９．Reported in the paper was the process for preparing scandium metal with the purity of 99.99%.The ScF3 raw material was obtained from oxide by fluoration method with NH4HF2,and then reduced with calcium metal to yield low purity scandium metal that was further purified with vacuum distilation to high purity.

关 键 词：氟化钪 钙热还原 蒸馏提纯 金属钪
