BORON NITRIDE POWDER AND PRODUCTION METHOD THEREFOR, BORON CARBONITRIDE POWDER, COMPOSITE MATERIAL, AND HEAT DISSIPATING MEMBER

摘要

One aspect of the present invention provides a boron nitride powder that contains aggregated particles formed through aggregation of primary particles of boron nitride. The cumulative pore volume of the boron nitride powder within a fine pore radius of 0.02-1.2 µm as measured by a mercury porosimeter is 0.65 mL/g or less.
