METHOD FOR PRODUCING BORON NITRIDE POLYCRYSTAL, BORON NITRIDE POLYCRYSTAL, CUTTING TOOL, WEAR-RESISTANT TOOL, AND GRINDING TOOL
A method of producing a boron nitride polycrystal includes: a first step of obtaining a thermally treated powder by thermally treating a powder of a high pressure phase boron nitride at more than or equal to 1300°C; and a second step of obtaining a boron nitride polycrystal by sintering the thermally treated powder under a condition of 8 to 20 GPa and 1200 to 2300°C.
