RESIN-IMPREGNATED BORON NITRIDE SINTERED BODY AND USE FOR SAME |
摘要 |
A resin-impregnated boron nitride sintered body having superior thermal conductivity and superior strength, and a resin-impregnated boron nitride sintered body having superior conductivity and small anisotropy of thermal conductivity are provided. A resin-impregnated boron nitride sintered body, including: 30 to 90 volume% of a boron nitride sintered body having boron nitride particles bonded three-dimensionally; and 10 to 70 volume% of a resin; wherein the boron nitride sintered body has a porosity of 10 to 70%; the boron nitride particles of the boron nitride sintered body has an average long diameter of 10µm or more; the boron nitride sintered body has a graphitization index by powder X-ray diffractometry is 4.0 or less; and an orientation degree of the boron nitride particles of the boron nitride sintered body by I.O.P is 0.01 to 0.05 or 20 to 100; and a resin-impregnated boron nitride sintered body, including: 30 to 90 volume% of a boron nitride sintered body having boron nitride particles bonded three-dimensionally; and 10 to 70 volume% of a resin; wherein: the boron nitride sintered body has a calcium content of 500 to 5000ppm; the boron nitride sintered body has a graphitization index by powder X-ray diffractometry of 0.8 to 4.0; the boron nitride sintered body comprises flake-like boron nitride particles having an average long diameter of 10µm or more; and an orientation degree by I.O.P is 0.6 to 1.4; are provided. |
