BORON NITRIDE SINTERED BODY, COMPOSITE BODY, METHOD FOR PRODUCING SAID BORON NITRIDE SINTERED BODY AND METHOD FOR PRODUCING SAID COMPOSITE BODY
Provided is a boron nitride sintered body including: a plurality of coarse particles each having a length of 20 µm or more; and fine particles smaller than the plurality of coarse particles, in which, when viewed in a cross-section, the plurality of coarse particles intersect with each other. Provided is a method for manufacturing a boron nitride sintered body, the method including: a raw material preparation step of firing a mixture containing boron carbonitride and a boron compound in a nitrogen atmosphere to obtain lump boron nitride having an average particle diameter of 10 to 200 µm; and a sintering step of molding and heating a blend containing the lump boron nitride and a sintering aid to obtain a boron nitride sintered body including coarse particles each having a length of 20 µm or more in a cross-section and fine particles smaller than the coarse particles.
