CUBIC BORON NITRIDE PARTICLE POPULATION WITH HIGHLY-ETCHED PARTICLE SURFACE AND HIGH TOUGHNESS INDEX
A cubic boron nitride particle population having highly-etched surfaces and a high toughness index is produced by blending a reactive metal powder with a plurality of cubic boron nitride particles to form a blended mixture. The blended mixture is compressed to form a compressed mixture. The compressed mixture is subjected to a temperature and a pressure, where the temperature is controlled to cause etching of the plurality of cubic boron nitride particles by reaction of cubic boron nitride with the reactive metal powder, thereby forming a plurality of etched cubic boron nitride particles. Also, the temperature and pressure are controlled to cause boron nitride to remain in a cubic boron nitride phase. Afterwards, the plurality of etched cubic boron nitride particles are recovered from the compressed mixture to form the particle population. Preferably, the particle population contains no hexagonal boron nitride.
通过将反应性金属粉末与多个立方氮化硼粒子共混以形成共混的混合物，制造具有高度腐蚀的表面和高韧性指数的立方氮化硼粒子群。将所述共混的混合物压缩以形成压缩混合物。使所述压缩混合物经受温度和压力，其中控制温度以通过使立方氮化硼与所述反应性金属粉末反应来引起所述多个立方氮化硼粒子的腐蚀，从而形成多个腐蚀的立方氮化硼粒子。此外，控制温度和压力以使氮化硼保持为立方氮化硼相。其后，从所述压缩混合物回收所述多个腐蚀的立方氮化硼粒子以形成所述粒子群。优选地，所述粒子群不包含六方氮化硼。
