摘要：

Formation of ultrafine titanium carbide powder from FeTiO3 (ilmenite)-Mg-C by combustion synthesis was reported. The laws of combustion and the effect of magnesium concentration on the characteristics of the product were discussed thermodynamically and investigated experimentally. It is found that the system is an intensively exothermic reaction and the start reaction temperature of the FeTiO3-Mg-C system is about 577.7 degrees C. When the molar ratio of ilmenite to magnesium is 1:4, ultrafine TiC powder after leaching is reasonably pure and shows a narrow particle size distribution. The average particle size of the final powder is 229.6 nm.
