金刚石多晶体的制造方法、金刚石多晶体、切削工具、耐磨工具以及磨削工具
Abstract:
本申请提供了一种金刚石多晶体的制造方法，该方法包括：第一步骤，其中在1300℃以上对高压相碳的粉末进行热处理，以得到经热处理的碳粉末；以及第二步骤，其中在12GPa以上25GPa以下和1200℃以上2300℃以下的条件下烧结经热处理的碳粉末，以得到金刚石多晶体。
Abstract(English):

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.
