摘　　要：Characterization of special morphology of periclase,corundum,spinel and mulllte/Gao Zhenxin,Zhang Wei,Huang Zhenwu,Wei Xiaohui〃Naihuo Cailiao.-2021,55(2):93 The crystal growth theory of periclase,corundum,spinel and mullite in different conditions was studied by means of high-resolution instruments,and the special-morphology crystals were characterized.Periclase of cubic system and euhedral spinel are typical cube and octahedron,and can also form any other shapes,such as joined crystallization and step growth,which are limited by the crystallization environment.Mullite belongs to orthorhombic system and has the long columnar crystallization habit.However,the euhedral development is often restricted by the environment.Mullite crystallizes(or peritectic reaction happens between corundum and liquid phase)into columnar shapes when there is a certain amount of liquid phase.The combination of mullite and corundum can exist in the form of simple symbiosis or peritectic reaction.periclase;corundum;spinel;mullite;microstructure.
