Title:
六方晶窒化ホウ素粉末及びその製造方法
Document Type and Number:
Japanese Patent JP7105701
Kind Code:
B2
Abstract:
A hexagonal boron nitride powder whose maximum absorption peak within the range of 3,100 to 3,800 cmof the diffuse reflectance fourier transform infrared spectrum is existent at 3,530 to 3,590 cmand which is able to provide high heat conductivity, dielectric strength and coper foil peel strength to a resin composition obtained by filling the powder into a resin, and a process for producing the above boron nitride powder by mixing together an oxygen-containing boron compound, a carbon source having a sulfur concentration of 1,000 to 10,000 ppm and an oxygen-containing calcium compound in a specific ratio and reduction nitriding the mixture.
