Abstract:
The present invention addresses the problem of providing agglomeraterd boron nitride particles which are suitable to be used as a thermally conductive filler for a heat dissipation sheet of a power semiconductor device, and which exhibit excellent isotropy of thermal conductivity, excellent degradation resistance, and excellent kneadability with respect to resin. The agglomerated boron nitride particles are obtained by agglomerating boron nitride primary particles. The agglomerated BN articles are characterized in that: a peak area intensity ratio ((100)/(004)) of a (100) plane to a (004) plane of the BN primary particles is 0.25 or more, and the average crystallite size of the BN primary particles obtained from a (002) plane peak of the BN primary particles is 375 Å or more.

Claim (Index 1):
An agglomerated boron nitride particle (\u201cagglomerated BN particle\u201d) constituted by boron nitride primary particles (\u201cBN primary particles\u201d),\n wherein a peak area intensity ratio ((100)/(004)) of a (100) plane to a (004) plane of the BN primary particles is 0.25 or more, the peak intensity ratio being obtained by subjecting, to a powder X-ray diffraction measurement, a pellet-shaped sample moulded at a moulding pressure of 0.85 ton/cm 2  using a 10 mm\u03c6 powder pellet moulding machine, the average crystallite size of the BN primary particles obtained from a (002) plane peak of the BN primary particles is 375 \u212b or more, the average crystallite size being obtained as a result of filling a glass sample plate having a depth of 0.2 mm with the agglomerated BN particles in such a way that the sample surface becomes smooth, and subjecting the agglomerated BN particles to a powder X-ray diffraction measurement, and an average particle diameter D 50  of the agglomerated BN particle is 26 \u03bcm or more.
