在ｐＨ和温度恒定的条件下，对硅灰石与盐酸反应动力学进行了实验研究。发现其反应动力学规律分为两阶段，初始阶段反应速度只与硅灰石总表面积有关；当反应率（Ｇ）达到一定值时，反应动力学符合固相多元体系的杨德尔速度方程。同时，对产物ＳｉＯ２物理状态和临界反应率（Ｇ）的意义进行讨论
The reaction kinetics of wollastonite and hydrochloric acid was studied experimentally at pH and temperature. The reaction kinetics was found to be divided into two stages. The initial reaction rate was only related to the total surface area of wollastonite. When the reaction rate (G) reached a certain value, the reaction kinetics was in accordance with the Youngdel velocity equation of the solid multi-component system. At the same time, the physical state of SiO2 and critical reaction rate (G) significance are discussed
