Title:
ALUMINA PARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/194158
Kind Code:
A1
Abstract:
The present invention provides alumina particles characterized by having a fixed card-house structure formed from three or more tabular aluminas and by having a mean particle diameter of 3 to 1,000 μm. In addition, the present invention provides alumina particles characterized by having a fixed card house structure wherein the three or more tabular aluminas intersect at a plurality of locations of two or more to be assembled in a state in which the directions of the tabular faces that intersect each other is disordered and by having a mean particle diameter of 3 to 1,000 μm.
