以石灰岩煅烧改性后得到的高纯氧化钙为钙质原料,水热合成硬硅钙石.结果表明,水热反应获得的优化工艺条件为CaO/SiO2摩尔比1:1,液固体积质量比30:1,反应温度220℃,反应时间16 h.为硬硅钙石型保温材料的应用,提供理论依据.%Chose limestone by calcined utilized as calcareous material to hydrothermal synthesizedxonotlite. The results show that the optimum conditions of hydrothermal synthesized is obtained at CaO/SiO2 molar ratio of 1:1, the hydrothermal temperature of 220 oC, the reaction time of 16 h, and the ratio of liquid-solid of 30:1. For the application of xonotlite thermal insulationmaterial,provide theoretical basis.
