Abstract

The sulfurization behavior of BaTiO₃fine particles was studied by thermogravimetry (TG) using CS₂. The sulfurization process of the fine particles was carried out at a heating rate of 1 °C min^-1by using a quartz springtype thermo balance in a CS₂/N₂gas flow. The obtained TG curve showed that the sulfurization of BaTiO₃fine particles started at around 380°C, which was considerably low compared with those found for two commercial BaTiO₃powders. The sulfurization occurred up to approximately 730°C with a maximun weight gain of 19.2% forming BaTiS₃. At further elevated temperatures, the BaTiS₃lost a small amount of sulfur to give BaTiS_3-xas a final product at 1000°C.
