METHOD FOR PRODUCING METALLIC TANTALUM OR NIOBIUM

摘要

A method for producing metallic tantalum or niobium without the use of fluorine through the reduction of a taltlum oxide niobium oxide in a dilution salt, wherein Na or Li is reacted with a molten dilution salt of one or more of chlorides of Ca, Sr and Ba, to form Ca, Sr or Ba, and the resultant Ca, Sr or Ba is used as a reducing agent. The method allows the production of a finely powdered product.
