Hexagonal boron nitride powder and method for producing the same, and composition and heat dissipation material using the same |
| abstract |
A hexagonal BN powder including aggregates of primary particles of hexagonal BN containing boron and oxygen as impurity elements at a content of 1.00 to 30.00% and 0 to 1.00% by mass, respectively, which has a peak A in a predetermined particle diameter range and a 50% volume cumulative particle diameter D 50 (d1) of 30.0 to 200.0 μl in a particle size distribution curve, and in which a ratio of a height (a1) of the peak A before treatment to a height (a2) of the peak A after treatment is 0.80 to 1.00 and a ratio of D 50 (d1) before treatment to D 50 (d2) after treatment is 0.80 to 1.00 when the hexagonal BN powder is ultrasonically treated under a predetermined condition for 1 minute. Also disclosed is a method for producing the hexagonal BN powder, a composition and a heat dissipation material. |
