摘要
在各种晶体的结构类型中BaTiO3 、CeO2 和NaCl 晶体的结构相对比较简单,但是它们的生长习性一直得不到合理的解释。如PBC理论很难合理解释BaTiO3 、NaCl 和CeO2 晶体的生长习性及习性变化。本文采用配位多面体生长习性法则研究了BaTiO3 晶体,CeO2 晶体和NaCl 晶体的理论生长习性。发现BaTiO3 晶体的生长习性为立方八面体;CeO2 晶体的生长习性为立方体;NaCl 晶体的生长习性为八面体,解释了溶液的过饱和度对NaCl 晶体的生长习性的影响。
Although the structure of BaTiO 3,CeO 2 and NaCl crystal is uncomplicated,their growth habit can not be reasonably explained.For example,their growth habit and habit change is not reasonably explained by PBC theory.In this paper,the theoretical habits of BaTiO 3,CeO 2 and NaCl crystal are investigated according to coordination polyhedron rule concerning growth habit.It is concluded that the growth habit of BaTiO 3 crystal is cubic octahedra; CeO 2 crystal is cube;NaCl crystal is octahedra.Moreover,the effect of the supersaturation of solution on growth habit of NaCl crystal is explained according to this rule.
