METHOD FOR PRODUCING POLYCRYSTALLINE DIAMOND BODY, POLYCRYSTALLINE DIAMOND BODY, CUTTING TOOL, WEAR-RESISTANCE TOOL AND GRINDING TOOL
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.
