Abstract

Abstract: Ultrafine Ti(C,N) powder was synthesized by inorganic sol-gel and carbothermal- reductionprocessing using TiO(OH)₂ and carbon black as starting materials. The thermodynamics of theprocess was analyzed. The effects of the ratio of raw materials, synthesizing temperature, holdingtime and the flow of N₂ on the composition of Ti(C,N) were investigated. Ti(C_1-x.,N_x) powderwith x values of 0.2-0.7 and an average particle size less than 100um can be obtained under properconditions.

Key words: sol-gel, titanium carbonitride, ultrafine powder
