Description

Technical Field

[0001] The utility model relates to the technical field of abrasive crushing equipment, in particular to an abrasive crushing device for boron nitride production. Background Art

[0002] Boron nitride has high thermal conductivity and excellent electrical insulation. In particular, boron nitride with a hexagonal crystal structure has a layered structure like graphite, is relatively easy to synthesize, and has excellent characteristics of thermal conductivity, electrical insulation, low dielectric constant, solid lubricity, chemical stability, and heat resistance. Therefore, boron nitride is expected to be used as a filler for resin compositions used in products such as heat sinks, thermally conductive insulating sheets, and sealing materials for electronic parts. However, boron nitride will hydrolyze due to reaction with water and degenerate into boron oxide with low thermal conductivity. In addition, boron nitride also produces corrosive ammonia when hydrolyzed.
