通过Reax FF反应力场能量最小化方法优化了几种硅酸钙矿物的晶胞参数和原子坐标,采用径向分布函数及配位数的计算,分析了以硅酸三钙、硅酸二钙、硅灰石、假硅灰石、硅钙石和斜方硅钙石等为代表的硅酸钙矿物的晶体结构,从而揭示了不同钙硅比和不同硅氧四面体链接方式的矿物化学性质及水化活性差异的机制。
With optimizing the crystal parameters by ReaxFF reactive force field minimization method, the radial distribution function and coordination numbers were calculated for tri-calcium silicate, dicalcium silicate, wollastonite,pseudo wollastonite,rankinite and kilchoanite to analyze the crystal structure of silicate minerals. Results shed light on the mechanism of different minerals' chemical properties and hydration activities.
