Abstract

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.
