Aluminum nitride boron nitride composite aggregate particle and its manufacturing method

摘要

PROBLEM TO BE SOLVED: To provide h-BN agglomerated particles which give larger thermal conductivity than a conventional one to a composite material composition.SOLUTION: Aluminum nitride-boron nitride composite agglomerated particles are formed by aggregating aluminum nitride primary particles and boron nitride primary particles. The composite agglomerated particles can be obtained by a production method including a reduction nitriding step of aluminum oxide.SELECTED DRAWING: Figure 4
