Title:
ALUMINA GRAIN, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/078292
Kind Code:
A1
Abstract:
Provided are an alumina grain and a preparation method therefor. The alumina grain is of a single-crystal structure and has an approximate regular octahedral stereoscopic morphology. Eight sides of the alumina grain belong to the {111}family of crystal planes of γ-state alumina, and the grain size is 5-100 μm. The alumina grain is unique in crystal plane exposure and distribution, simple and feasible in preparation, and low in cost, and has higher operability, and thus has good application prospect in the field of catalysis and adsorption.
