Research Abstract

We conducted high pressure and temperature experiments to synthesize the conductorial polycrystalline born-doped diamond and to test the performance of boron-doped diamond as heating materials. As a result, pre-synthesized boron-doped diamond works well as heating materials at high pressure. Because of conductivity, an electric discharge machining is useful for born-doped diamond.
