METHOD FOR PRODUCING BOEHMITE PARTICLES AND METHOD FOR PRODUCING ALUMINA PARTICLES

摘要

A method for producing boehmite particles includes subjecting powder of aluminum hydroxide to hydrothermal reaction together with a nucleation agent, thereby obtaining boehmite particles having an average primary particle size of 0.6 µm or less and including primary particles each having a hexahedral shape.
A method for producing alumina particles includes: drying the boehmite particles produced by the above described method; calcining the boehmite particles, which have been dried, to obtain alumina particles; and disintegrating the obtained alumina particles.
