HSC Chemistry thermodynamic analysis software, thermo-gravimetric and differential scanning calorimetric methods were used to analyze the evolution process of the reduction and carbonization of TiO and WO by carbon under the condition of an inert atmosphere. The results show that due to the increased reaction activity of the raw materials by ball-milling and the existence of gas-solid synergetic reaction, the actual reaction temperature is lower than the one of the thermodynamic calculation result. As the temperature increases, TiO and WO are gradually reduced and carbonized in the order of TiO→TiO→TiO→TiO→TiO→TiC and WO→WO→W→WC→WC, respectively. The final reaction temperature is suggested to be above 1400 °C to speed up the kinetic process of the reaction.
