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 BaTiS3-xas a final product at 1000°C.
