Synthesis of Ti(C,N) Powder by Inorganic Sol-Gel Processing
溶胶-凝胶工艺合成Ti(C,N)超细粉末

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(C1-x.,Nx) powderwith x values of 0.2-0.7 and an average particle size less than 100um can be obtained under properconditions.
