METHOD OF COMPLEX CARBONITRILE PRODUCING Russian patent published in 1994 - IPC

Abstract RU 2023656 C1

FIELD: chemical technology. SUBSTANCE: method involves mixing of powders of titanium carbonitride (5.0-20.44 wt.-%), titanium oxide, metallic tungsten, tantalum pentoxide and carbon black taken at the excess of stoichiometric one but not more than 0.5 wt.-%. Mass ratio TiO2:TiCN = 0,5-3,0:TiCN = 0.5-3.0. Mixture is subjected for thermal treatment at 2100 C in nitrogen atmosphere. Complex carbonitride has oxygen and free carbon at concentration 0.04-0.06 wt.-%. Method is used for making of sintered solid alloys. EFFECT: improved method of producing. 1 tbl
