METHOD OF NIOBIUM ALLOYS PRODUCTION Russian patent published in 1994 - IPC

Abstract RU 2022043 C1

FIELD: chemical industry. SUBSTANCE: before reduction, mixture of chlorides is subjected to holding under pressure of 0.1 - 0.2 MPa during 0.5 - 9.5 hour under temperature of 10 - 50 C over temperature of mixture melting. Reduction is exercised with magnesium use level of 20 - 55 % and before dismantling of separation apparatus treatment by mixture of inert gas and air is carried out during 0.3 - 1.0 hour for passivation of dispersing sublimates. Vacuum separation is carried out in presence of getter with ratio of reaction mass to getter mass as 1 : 1 - 1 : 5. EFFECT: method is used to produce niobium alloys. 2 cl
