Abstract:
A hexagonal boron nitride powder having an average longer diameter (L) of primary particles in the hexagonal boron nitride powder of 10 μm or less, an average thickness (D) of the primary particles in the hexagonal boron nitride powder of 0.20 μm or more, a ratio of the average longer diameter (L) to the average thickness (D), [L/D], of 3.0 or more and 5.0 or less, and a content of primary particles having a ratio of a longer diameter (l) to a thickness (d), [l/d], of 3.0 or more and 5.0 or less of 25% or more. Also disclosed is a method for producing the hexagonal boron nitride powder, and a resin composition and a resin sheet each containing the hexagonal boron nitride powder.

Claim (Index 4):
The hexagonal boron nitride powder according to  claim 1 , wherein the hexagonal boron nitride powder comprises an aggregate of two or more primary particles, and when the hexagonal boron nitride powder is put through a sieve having an opening of 106 \u03bcm, the hexagonal boron nitride powder passing through the sieve has a 50% volume cumulative particle size D 50 (1) of 25 \u03bcm or more and 100 \u03bcm or less, and a dispersion liquid obtained by dispersing in water the hexagonal boron nitride powder passing through the sieve has a 50% volume cumulative particle size D 50 (2) of 15 \u03bcm or less after the dispersion liquid is subjected to an ultrasonic treatment for 3 minutes.
