| Abstract: | 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. |
