Mechanical properties of polycrystalline cBN sintered bodies synthesized by using submicron cubic boron nitride(cBN)powder and hexagonal BN(hBN)powder as starting materials under high pressure and high temperature have been investigated by hardness and the scanning electron microscopy(SEM)in the pressure range of 6.5–11GPa and 1750 ℃.
