    Dec 17, 20130183;32;Brian Clegg. Just as synthetic diamonds are made from graphite, the diamond like cubic boron nitride is produced from the basic hexagonal version, by applying extreme pressure and temperature. The result is crystals that are nearly as hard as diamond, and beat their carbon brethren hands down on some other capabilities.

    Diamond and Cubic Boron Nitride. Diamonds basic foundation is carbon. CBNs basic foundation is a combination of Boron and Nitrogen.The crystal structure of both are the same with all unit cells in the diamond crystal being of carbon atom, and the CBN crystal being of the boron atom alternating equally with the Nitrogen atom.
