Boron Nitride

Boron Nitride is a thermally and chemically resistant refractory Boron Product compound of boron and nitrogen with the chemical formula BN. Boron Nitride Ceramic exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among Hexagonal Boron Nitride polymorphs, and is therefore used as a lubricant and an additive to cosmetic products. The cubic (zincblende aka sphalerite structure) variety analogous to diamond is called c-Boron Nitride Powder; it is softer than diamond, but its thermal Pvc Resin and chemical stability is superior. The rare wurtzite oron Nitride Coating modification is similar to lonsdaleite but slightly softer than Ethylene-Vinyl Acetate the cubic form.

Because of excellent thermal and chemical stability, boron nitride ceramics are used in high-temperature equipment. Boron nitride has potential use in nanotechnology.

Hexagonal Boron Nitride 50nm (along with Si3N4, NbN, and BNC) is reported to show weak fibrogenic activity, and to cause pneumoconiosis when inhaled in particulate form. The maximum concentration recommended for nitrides of nonmetals is 10 mg/m3 for BN and 4 for AlN or ZrN.
