| 摘 要： | 常压水热条件下,以天然高岭土为原料,制备莫来石复相晶体实验观察到莫来石晶体呈柱状生长习性.用Materials Studio 4.4 CASTEP(Cambridge serial total energy package)程序,对莫来石晶体的特征显露面族(001),(210),(110)和(120)晶面表面能进行理论计算,进而分析各晶面生长速度与习性关系.计算得出其表面能大小依次为0.337,0.022,0.217和0.039keVnm–2,根据居里-吴尔夫原理,则各晶面生长速度为V(001)>V(110)>V(120)>V(210),表明莫来石晶体能够沿c轴生长成柱状形态.莫来石晶体模型表面能计算结果合理解释了实际莫来石的柱状生长习性.
