Remarks Price largely depends on the geometry of the product but is approximately 5 or 10 times as high as steel. HPBN stands for High Pressure Boron Nitride. The boron nitride which is described in this record has a simular structure as graphite (hexagonal). This hexagonal boron nitride is soft and platelike. There also exists a cubic form of boron nitride (beta-BN or borazon), of which the structure is simular to diamond. The cubic boron nitride is much harder than the hexagonal boron nitride, and is used as grinding material or for the manufacture of metal-cutting tools. The properties of this material are almost equal to diamond, and so is the price.
