| Abstract: | Diamond was synthesized by using B4C as the carbon source in the Ni70Mn25Co5-B4C system under 5.7～6.0 GPa and 1 370～1 500 ℃.This is the first example using pure B4C as the carbon source to synthesize diamonds, which is dark and contains more than 1wt% of boron. The synthesized diamond has a grain-size of about 20 μm, is mainly a combination of cubic and octahedral bodies. After reaction, Ni2B compounds are found to exist in the metallic catalyst left, and B13C2 compounds with rich boron in the non-metallic remainders. |
