Abstract

A polycrystalline superhard material comprises a mass of diamond, graphite or cubic boron nitride particles or grains bonded together by ultrathin inter-granular bonding layers, the inter-granular bonding layers having an average thickness of greater than about 0.3 nm and less than about 100 nm. There is also disclosed a method for making such a polycrystalline superhard material.
