Boron nitride sintered body, composite body, method for producing same, and heat dissipation member
Provided is a boron nitride sintered body containing a plurality of coarse particles having a length of 20 [mu] m or more and fine particles smaller than the plurality of coarse particles, the plurality of coarse particles crossing each other when viewed in a cross-section. Provided is a method for producing a boron nitride sintered body, the method comprising: a raw material preparation step for obtaining bulk boron nitride having an average particle diameter of 10-200 [mu] m by firing a mixture containing boron carbonitride and a boron compound in a nitrogen atmosphere; and a sintering step in which a complex containing the bulk boron nitride and a sintering aid is molded and heated to obtain a boron nitride sintered body containing coarse particles having a cross-sectional length of 20 [mu] m or more and fine particles smaller than the coarse particles.
本发明提供氮化硼烧结体，其含有具有20μm以上的长度的多个粗大粒子、和比多个粗大粒子小的微细粒子，在对截面进行观察时，多个粗大粒子彼此交叉。提供氮化硼烧结体的制造方法，其具有：原料制备工序，将包含碳氮化硼和硼化合物的混合物在氮气氛下进行烧成，得到平均粒径为10～200μm的块状的氮化硼；和烧结工序，进行包含块状的氮化硼和烧结助剂的配合物的成型及加热，得到含有截面上的长度为20μm以上的粗大粒子和比粗大粒子小的微细粒子的氮化硼烧结体。
