Combustion synthesis of Ti2SC

Ti/S/C powders were used as raw material for the combustion synthesis of Ti2SC. The results showed that Ti2SC was the main phase of the product of the 2Ti/S/C powders used for the synthesis. Furthermore, certain amounts of TiC and Ti3S4 were found in the product. Excess S addition improved the synthesis of Ti2SC. Scanning electron microscopy indicates that the lamellar Ti2SC grains had lengths ranging from 20 mu m to 30 mu m.
