Preparation of SiO2 Coated Ce2S3 Red Pigment with Improved Thermal Stability

摘要：

　　SiO2 coated Ce2S3 red pigment was prepared in ethanol/H2O system via sol-gel method and TEOS were used as silica sources.XRD,SEM,EDX,UV-visible spectrophotometer and automatic colorimeter were used to investigate the properties of the samples.The results show that the compact SiO2 film forms on the surface of Ce2S3 pigment at a cerium silicon molar ratio of 2.The thermal stability temperature of Ce2S3 pigment has been improved to 450 ℃ after SiO2 coating.In addtion,the color of Ce2S3 pigment hasn”t been affected significantly through coating colorless and transparent SiO2 and it can be used as safe red pigment in higher temperature fields.
