CUBIC BORON NITRIDE SINTERED BODY, TOOL COMPRISING CUBIC BORON NITRIDE SINTERED BODY, AND PRODUCTION METHOD FOR CUBIC BORON NITRIDE SINTERED BODY
A cubic boron nitride sintered material comprising cubic boron nitride particles and a binder phase, in which the binder phase contains aluminum nitride and aluminum diboride, a content proportion of the cubic boron nitride particles is 70 vol% or more and 97 vol% or less with respect to the entire cubic boron nitride sintered material, the cubic boron nitride sintered material has a volume resistivity of 5 × 10-3 Ωcm or less, in a case where X-ray diffraction measurement is performed on an arbitrary surface or arbitrary cross section of the cubic boron nitride sintered material, a rate of a peak intensity derived from metallic aluminum with respect to a peak intensity derived from the cubic boron nitride particles is less than 1.0%, the cubic boron nitride particles include fine particles having a particle diameter of 2 µm or less and coarse particles having a particle diameter of 5 µm or more, the coarse particles optionally include ultra-coarse particles having a particle diameter of more than 12 µm and, with respect to the entire cubic boron nitride particles, a content proportion α of the fine particles is 10 vol% or more, a content proportion β of the coarse particles is 30 vol% or more, a content proportion γ of the ultra-coarse particles is 25 vol% or less, and a total of the content proportion α of the fine particles and the content proportion β of the coarse particles is 50 vol% or more and 100 vol% or less.
