摘要: 以硅灰石为核心,采用化学沉淀法在其表面均匀包覆一层纳米TiO2,形成了硅灰石复合钛白。包覆过程中硅灰石的预处理是关键一步。经XRD,IR,SEM,TEM和XPS对复合钛白进行表征,结果表明,包覆完全的硅灰石复合钛白性能与钛白粉相当。

关键词: TiO2, 硅灰石, 复合钛白, 包覆

Abstract: The composite of nano-titania/wollastonite were prepared by precipitating titania on the surface of wollastonite. Wollastonite powders must be pretreated in the process of coating. The composites were characterized by XRD, IR, SEM, TEMand XPSmethods. All the results revealed that the wollastonite was fully coated and the properties of the composite was similar to that of titania.

Key words: Titania, Wollastonite, Composite, Coating
