BORON NITRIDE SINTERED BODY, COMPOSITE, METHODS FOR PRODUCING SAME, AND HEAT DISSIPATION MEMBER
Provided is a boron nitride sintered body including boron nitride particles and pores, in which an average pore diameter of the pores is less than 2 μm. Provided is a method for manufacturing a boron nitride sintered body, the method including: a nitriding step of firing a boron carbide powder in a nitrogen pressurized atmosphere to obtain a fired product containing boron carbonitride; and a sintering step of molding and heating a blend containing the fired product and a sintering aid to obtain the boron nitride sintered body including boron nitride particles and pores, in which the sintering aid contains boron oxide and calcium carbonate, and the blend contains 1 to 20 parts by mass of a boron compound and a calcium compound in total with respect to 100 parts by mass of the fired product.
