Abstract

The geometric model of Al2O3 grain is designed based on its crystal character, through randomly 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.

Key words： platelet Al2O3 grain; geometric model; aspect ratio; slenderness ratio
