Description
よって本発明は、ターゲット用高純度チタン材の製造に好適なニッケルやクロムの含有率の低いスポンジチタン材の製造を可能とする方法を提供することを目的とする。
炭素鋼で内張りした7tバッチサイズのステンレス鋼製容器に、ニッケル濃度1ppmの溶融マグネシウムを容器容量の20%まで装入し、0.1kg/cm2Gまで減圧した。この状態で30分静置後、溶融マグネシウムを全量抜き出し、再度、ニッケル濃度1ppmの溶融マグネシウムを装入し、四塩化チタンの滴下を開始してスポンジチタンの製造を行った。このようにして製造したスポンジチタン中のニッケル濃度を調べたところ、1ppmであり、市場から要求される品質特性を満足した。
[実施例2]
溶融マグネシウムによる還元反応容器の洗浄を行わない以外は、実施例1の条件と同様にしてスポンジチタンを製造し、このスポンジチタンのニッケル濃度を調べたところ、3ppmであった。
Claims (1)
- 四塩化チタンを溶融マグネシウムで還元してスポンジチタンを製造する方法において、還元反応容器に装入した溶融マグネシウムを減圧下で加熱して蒸気とし、この蒸気を前記還元反応容器の内面で還流させて、前記還元反応容器内面近傍に含まれるニッケル成分を前記還流マグネシウム中へ溶出させて移行させた後、前記溶融マグネシウムを容器外に抜き出し、次いで、新規な溶融マグネシウムを装入して四塩化チタンとの還元反応を開始することを特徴とするスポンジチタンの製造方法。
