Abstract
Cubic boron nitride composite particles containing hard microparticles dispersed in cubic boron nitride particles. The hard microparticles have an average particle size of about 10 nm to about 10 &mgr;m and a particle size equal to or smaller than one-third of the particle size of any of the cubic boron nitride particles, and the amount of the hard microparticles dispersed in the cubic boron nitride particles is from about 1% to about 50% by volume.
