本文运用X光电子能谱法(XPS法)及其它表面分析方法,对三种结晶程度不同的水化硅酸钙的表面特性进行了研究。结果表明,水化硅酸钙的表面恃性与结晶程度有一定的相关性。结晶程度越差,用XPS法测得的C/S比和电子结合能越大,颗粒表面的固体碱量也增加,同时相应的ζ电位的零电点出现在浓度较高的碱性溶液中。
Abstract：X-ray photoelectron spectroscopy(XPS) and other surface analytical techniques were used to study the surface characteristics for three kinds of hydrated calcium silicates of different crystallinities. The experimental results show that the surface characteristics are correlated with crystallinity of hydrated calcium silicate. The poorer the crystallinity, the greater the C/S ratio; the greater the electron binding energy value determined by XPS, the larger the quantity of solid base on the surface. At the same time, the corresponding point of zero charge(PZC) of ζ-potential appears in a more concentrated basic solution.
