Abstract

Nano-crystalline Ti2SC powders were synthesized by a molten salt method with TiS2/3Ti/2C powders as raw materials and KCl–NaCl as the molten salt medium under argon protection. The effect of heat treatment temperature on the composition and morphology of Ti2SC powder was studied. Ti2SC powder can be synthesized at a relatively low temperature by the molten salt method. A high content of Ti2SC powder can be obtained at 1150 °C for 1.5 h. The particle size of the powder was 22.6 nm. Scanning electron microscopy and transmission electron microscopy showed that nano-sized Ti2SC had an average particle size of 20–30 nm.
