Diamond has excellent physical and chemical properties

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  cutting tools affinity, high insulation resistance and good biological compatibility, this makes diamond the most potential to become the 21st century's new

Functional cubic boron nitride . However, due to scarce and expensive natural 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, therefore has wide

Range of applications and business prospects.
