Abstract
PURPOSE:To obtain a high-quality composite carbon nitride of fine powder, useful for producing cermet, by heating a mixture of TiO2, Ta2O5, MoO3, etc., in a H2 atmosphere and reacting in a N2 atmosphere at a specific temperature. CONSTITUTION:TiO2 is mixed with Ta2O5, WO3, MoO3 and carbon powder to give a mixture, which is heated in a H2 atmosphere under 10<-3>Torr-10atm. and heated at 1-100 deg.C/min rate of heating in the whole temperature range from normal temperature (beginning of heat treatment) to the maximum attained temperature of 1,500-2,100 deg.C. When temperature is reached to 1,200-1,500 deg.C, the atmosphere is changed by N2 feed, the reaction system is heated, pressure in the N2 atmosphere is maintained at 30Torr-10atm. and the reaction system is successively heated. Then the reaction system is reacted at the maximum attained temperature of 1,500-2,100 deg.C for 10min-5hr to give a composite carbon nitride of Ti, Ta, W and Mo.
