Evaluation of Three-dimensional Shape of Platelike Al_2O_3 Grains

Rui Qiao

Abstract

The geometric model of Al_2O_3 grain is designed based on its crystal character,through ran- domly slicing the grain model with a given slenderness ratio with the emulation slicing system,the grain random section parameter-aspect ratio can be gotten.Then,the relationship between three-dimensional shape parameter of crystals and its two-dimensional section shape parameter can be established.In practical application,utilizing the relationship,three-dimensional shape of grains can be queried by measuring grains section parameter.
