Preparation of Vermiculite-like Layered Silicate by Hydrothermal Method
摘要
Abstract
Vermiculite-like layered silicate has been synthesized by hydrothermal method, the effects of reaction temperature, reaction time and silicon source on the structure and morphology have been investigated. The reaction temperature has an important influence on the structure of materials; the degree of crystallinity has been significantly improved as the reaction temperature increases. When temperature is increased to 340 ℃, there are stratification and impurities of Sodium Aluminium Silicate Hydrate in samples. The degree of crystallinity improves and the size of lamina increases with increasing the reaction time. When the reaction time is increased to 36 h, the impurities are observed in the samples. The influences of silicon resource on the structure are much less than the crystallinity. The results show that the optimum temperature is 300 ℃, the optimum reaction time is 24 h, and the optimum silicon source is fumed silicon dioxide.关键词
