Ceramics Cubic Boron Nitride

Its unique properties from high heat capacity and outstanding thermal conductivity to easy machinability lubricity low dielectric constant and superior dielectric strength make boron nitride a truly outstanding material.

Ceramics cubic boron nitride.

Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula bn it exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. 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. 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 has out standing thermal characteristics.

Boron nitride is a synthetic technical ceramic material which is available in powder solid aerosol and liquid forms. 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. The cubic boron nitride cbn variety analogous to diamond has high hardness which is inferior only to diamond. The hexagonal form boron nitride hbn corresponding to graphite is the softest and most stable form among bn polymorphs and is therefore used as lubricant and an additive to cosmetic products.

High thermal conductivity and excellent thermal shock resistance. Boron nitride is an advanced synthetic ceramic material available in powder solid liquid and aerosol spray forms.
