Thermogravimetry Analysis and Kinetic Characteristics of Ti(C,N) Formation by Slag-Coke Reaction

Abstract:

The non-isothermal experiments of TiO2 reduction to Ti(C,N) were conducted by a comprehensive thermal analyzer in Ar and N2 atmospheres. The mechanism of Ti(C,N) generation was analyzed and the kinetic parameters in different atmospheres were calculated. The results showed that Ti(C, N) formation process was controlled by interface chemical reaction, and the existence of nitrogen would favor the formation of Ti (C, N). TiC transforming into TiN occurred at a temperature above 1200°C.
