摘　　要：本工作用锡和锌两种溶胶对硅灰石进行表面处理。用酸碱测定、X-射线光电子能谱(XPS)、傅里叶变换红外光谱(FT-IR)、粒度分析、比表面测定和扫描电子显微分析(SEM)等方法研究了溶胶处理对硅灰石表面化学性质和物理性质的影响情况。结果表明经过溶胶处理,锡或锌是以氧化物的形式包覆在硅灰石的表面,使得硅灰石的表面组成、形貌和酸碱性都发生了变化。In this paper, wollastonitc is modified with two kinds of hydrosol: Tin hydrosol and Zinc hydrosol. The effect of hydrosol treatment on the surface properties of wollastonite has been investigated with X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared (FT-IR) particle size analysis, measurement of specific surface area and scanning electron micrograph(SEM). The results suggest that tin or zinc encapsulates wollastonite in the form of oxide after the hydrosol treatment. The surface composition, surface topography and acid-base properties are changed by hydrosol treatment.
