  • A system of VC powder and Ni70Mn25Co5 alloy in weight ratio of 1∶6 was treated under high pressure of 6.0 GPa and high temperature of 1 500 ℃ for 20 min. X-ray diffraction of the sample indicates that diamond and graphite formed respectively with decomposition of the VC. Observation in SEI, WDX and EDX shows that many diamond crystals are synthesized, which have rugged surfaces mostly, and the average grain size is about 20 m。
