Cubic Boron Nitride is the second hardest known material, diamond being the hardest.
Unlike diamond, CBN is not found in nature, but is a manufactured material. The abrasive
particles are synthesized under conditions similar to those used to produce synthetic
diamond. In grinding wheels and other tools it is used to machine hard, mainly ferrous metals
in the automotive and aerospace industries. Cubic Boron Nitride is also used to manufacture
polycrystalline products.
