本文从结晶化学角度出发，研究了ＡＢ和Ａ２Ｂ３和ＡＢＯ３型氧化物晶体中的氧配位八面体的结晶方位与晶体结晶形貌之间的关系，提出晶体的结晶形貌是受晶体中负离子配位多面体结构和结晶方位所制约的，配位多面体顶角所对向的晶面生长速率最快，而面所对向的晶面生长速率最慢，配位体的棱所对向的晶面，生长速率居于两者之间，负离子配位多面体在晶体的各个面族上连接的稳定性，决定了晶面的显露程度和晶体的结晶形貌． In this paper, from the crystallization chemistry point of view, AB and A2B3 and ABO3 type oxide crystal oxygen coordination octahedral crystal orientation and the relationship between the crystal morphology, the crystal morphology is determined by the crystal anion Polyhedral structure and orientation of the crystal orientation, the coordination polyhedral vertex angle of the plane opposite to the fastest growth rate, and the plane opposite to the slowest growth rate of the crystal plane, the orientation of the crystal face of the crystal face , The growth rate of living in between the two, anion coordination polyhedron in the various facets of the crystal on the stability of the connection, determines the extent of the crystal face and crystalline crystal morphology.
