METHOD FOR PRODUCING DIAMOND POLYCRYSTAL AND, DIAMOND POLYCRYSTAL
Provided is a method for producing a polycrystalline diamond body, the method including a first step of heat-treating a powder of high-pressure-phase carbon at higher than or equal to 1300°C to obtain a heat-treated carbon powder, and a second step of sintering the heat-treated carbon powder under conditions of greater than or equal to 12 GPa and less than or equal to 25 GPa and higher than or equal to 1200°C and lower than or equal to 2300°C to obtain a polycrystalline diamond body.
