Ceramics Cubic Boron Nitride

Boron nitride is an advanced synthetic ceramic material available in powder solid liquid and aerosol spray forms.

Ceramics cubic boron nitride.

Cubic boron nitride cbn next only to diamond in hardness knoop hardness 4700 kgf mm 2 is an unusual material in that it does not exist in nature. Boron nitride is an advanced synthetic ceramic material available in solid and powder form. High thermal conductivity and excellent thermal shock resistance. Boron nitride has out standing thermal characteristics.

Its unique properties from high heat capacity and outstanding thermal conductivity to easy machinability and superior dielectric strength make boron nitride a truly outstanding material. Boron nitride is a synthetic technical ceramic material which is available in powder solid aerosol and liquid forms. The cubic boron nitride cbn variety analogous to diamond has high hardness which is inferior only to diamond. The hexagonal form corresponding to graphite is the most stable and soft among bn polymorphs and is therefore used as a lubricant and an additive to cosmetic products.

In solid form it can be machined easily with ordinary metalworking tools. Synthesis of cbn involves the structural transformation of boron nitride from hexagonal to cubic form similar to diamond at high temperature high pressure hp ht in the presence of a.
