A superhard material is a material with a hardness value exceeding 40 gigapascals GPa when measured by the Vickers hardness test. Highly incompressible solids with high electron density and high bond covalency. As a result of their unique properties, these materials are of great interest in many industrial areas including, abrasives, polishing and cutting tools and wearresistant and protective coatings.The hardness of a material is directly related to its incompressibility, elasticity and resistance to change in shape. A superhard material has high shear modulus, high bulk modulus and does not deform plastically. Should have a defectfree, isotropic lattice. This greatly reduces structural deformations that can lower the strength of the material. Traditionally, highpressure and hightemperature HPHT conditions have been used to synthesize superhard materials, but recent superhard material syntheses aim at using less energy and lower cost materials.Vickers hardness of selected hard materials Material Vickers hardness GPa Diamond 115 cBC2N 76 cBN 48 OsB2 37 B4C 30 ReB2 20 Superhard material industry chain mainly involves the following three aspects: monocrystalline superhard materials including diamond, cubic boron nitride, etc., composite superhard materials including clad sheet for cutting tools, clad sheet for oil/gas, clad sheet and wire drawing die blanks used for coal/mining and superhard materials and tools including diamond saw blades, polycrystalline diamond drawing dies and drills, etc.
