Abstract

PURPOSE:To obtain an aluminum nitride powder having excellent fluidity, by decomposing hydrophobic group of surfactant of a mixed powder containing the aluminum nitride powder and surfactant and adding water-soluble organic high polymer compound thereto and granulating the blend. CONSTITUTION:The granulated product obtained by adding a surfactant to a mixed powder containing an aluminum nitride powder and an additive such as sintered auxiliary, decomposing hydrophobic group of the surfactant and granulating the blend using water-soluble organic high polymer compound as a binder. Heating or corona discharge is carried out in order to decompose and stabilize the hydrophobic group of the surfactant. The heating temperature is preferably at 100-200 deg.C. When the heating temperature is <100 deg.C, stabilization is not sufficiently carried out, dispersion to water is reduced and the granulation can not be carried out. When the heating temperature exceed 200 deg.C, almost all of the surfactant is removed and though dispersion to water is improved, oxygen in the aluminum nitride after granulation is increased.
