INSULATION HEAT DISSIPATION SHEET AND GRANULATION METHOD FOR BORON NITRIDE

摘要

PROBLEM TO BE SOLVED: To provide an insulation heat dissipation sheet which is advantageous in productivity and cost, and excellent in heat conductivity and electric insulation properties, and a granulation method for boron nitride used therefor.SOLUTION: According to a granulation method of boron nitride, the boron nitride is made flow within a flowing layer and granulated while spraying a silane coupling agent containing the amino group. Therefore, a heat dissipation sheet can be provided which is advantageous in productivity and cost and excellent in heat conductivity and an electric insulation property.
