摘要: Metallic niobium or metallic tantalum is produced by a process which comprises bringing a fluorine containing com pound of niobium or tantalum:
(A) into contact with a gas comprising hydrogen at a temperature of at least 400°C; or
(B) into contact with metallic aluminium, metallic magnesium or metallic lead, at a temperature of at least 300°C;
to convert the fluorine containing compound into the corres ponding metal.摘要翻译: 金属铌或金属钽通过包括使铌或钽的含氟化合物(A)在至少400℃的温度下与包含氢的气体接触的方法来生产; 或(B)在至少300℃的温度下与金属铝,金属镁或金属铅接触; 以将含氟化合物转化为相应的金属。
