Abstract： Titanium vanadium carbide powders were synthesized by carbothermic reduction process, using ammonium metavanadate, graphite and titanium as raw materials. The reaction process and phase evolution during preparing titanium vanadium carbide were investigated using TGDSC, XRD and SEM. The results show that the reaction temperature and carbon contents have great influence on formation of TiVC2. Increasing the carbon contents is benefit to accelerate the carbothermic reaction process. When the carbon content is higher, the products are VC and TiC. When the reaction temperature is higher than 1 500 ℃ and the carbon content is lower than 24.66%, TiVC2 solid solution can be obtained.
Keywords: carbothermic reduction; titanium vanadium carbide; solid solution
