Title:
METHOD FOR PRODUCING HEXAGONAL BORON NITRIDE POWDER, AND HEXAGONAL BORON NITRIDE POWDER
Document Type and Number:
WIPO Patent Application WO/2021/085223
Kind Code:
A1
Abstract:
Provided is a production method by which the filling property of a hexagonal boron nitride powder, which contains hexagonal boron nitride particles having a low aspect ratio, with respect to a resin can be improved while maintaining the characteristic of having small thermal conductivity anisotropy. This method for producing a hexagonal boron nitride powder comprises crushing, by using a means that does not substantially involve grinding primary particles, a hexagonal boron nitride raw material powder, which contains hexagonal boron nitride particles having an aspect ratio of 1.5-5.0 and an aggregate including hexagonal boron nitride particles having an aspect ratio of greater than 5.0.
