Diamond has excellent physical and chemical properties

High hardness, high thermal conductivity and high optical transmission properties, high chemical stability, a wide band gap, negative electron affinity, high insulation resistance and good Diamond blade  compatibility, which makes the most of diamond in the 21st century the potential of new functional materials. However, due to scarce and expensive cubic boron nitride diamond, can be applied to mass production, thus limiting the application of the diamond people. Synthetic diamond has the same structure as natural diamond and a comparable performance, and low cost, thus has a wide range of applications and business prospects.
