Abstract

　Ｃａによる還元反応を用いたＴｉ又はＴｉ合金の製造方法であって、ＣａＣｌ２を含み且つＣａが溶解した溶融塩を反応容器１内に保持し、その溶融塩中のＣａにＴｉＣｌ４を含む金属塩化物を反応させて前記溶融塩中にＴｉ粒又はＴｉ合金粒を生成させる還元工程と、前記溶融塩中に生成されたＴｉ粒又はＴｉ合金粒を前記溶融塩から分離する分離工程７とを含む方法である。反応容器１外へ抜き出されたＣａＣｌ２をＣａとＣｌ２とに電気分解し、生成されたＣａを反応容器１内でのＴｉ又はＴｉ合金の生成反応に使用する電解工程８を付加するのが望ましい。電解工程８において、陰極に溶融Ｃａ合金からなる合金電極を用いれば、電流効率の向上に効果的であり、溶融塩のＣａ濃度を高めるためのＣａの移送媒体として有効に利用することもできる。この方法によれば、高純度の金属Ｔｉを能率よく経済的に製造することができる。
