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. 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.

The purity of the boron powder at this stage is 85.9%-wt (M-B-86), comprising 10-12%-wt Mg, as well as small amounts of boron oxide and sub-oxides as further impurities. Further purifiion of the powder can be achieved by reduction of the Mg content.
Silica, as sand, is a principal ingredient of glass--a material with excellent mechanical, optical, thermal, and electrical properties. Ultra high purity silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics industry.
