本文运用负离子配位多面体生长基元理论模型讨论了负离子配位多面体在异质同构和同质异构晶体中的结晶方位和其形态之间的关系,发现晶体的生长习性与负离子配位多面体在不同面族上相互联结的稳定性密切相关.负离子配位多面体以顶角相联最稳定,以边相连次之,以面相连最不稳定.同时,本文用负离子配位多面体生长基元理论模型对极性晶体ZnO和ZnS的生长习性也做了一定的解释.

Based on the theoretical model of anionic coordination po1yhedron growth units,this paper discussed the relationship between the crystal morphology and the orientation of anionic coordination polyhedra in the isomer (rutile,brookite and anatase)and allomer (rutile and cassiterite;corundum,hematite and ilmenite). It was found that the crystal habits of these crystals were related to the stability of combination of anionic coordination polyhedron growth units with different faces.The combination of the vertexes is the best stable,the edge second and the face third.Furthermore,the morphology of polar crystals ZnS and ZnO was also interpreted in the viewpoint of anionic coordination polyhedron growth units.
