Boron nitride
It’s been around for more than a century. As a high-temperature grease, hexagonal boron was the first application. White graphite is a common name because of its similarity to graphite in terms of both its structure and properties.
Most properties of boron materials are better than those of carbon materials. The following properties are found in hexagonal boron Nitride: Low friction coefficient; good high temperature stability; good thermal shock resistance; high strength; high thermal conductivity.
Boron Nitride is a hexagonal system of crystals. The most common one is the graphite crystal lattice. There are other forms as well, such as: Rhombohedral Boron Nitride (rBN), Cubic Boron Nitride (cBN), or wurtzite boronnitride.
It is a semiconductor material with a wide band-gap (band-gap of 6.4 eV). Cubic-boron nitride exhibits high thermal conductivity, good resistivity, low dielectric, high breakdown field, dual-type-doping, and excellent electrical properties. They all share a wide band-gap, which makes them ideal for electronics that operate in extreme environments.
In comparison with SiC or GaN, diamond and cubic-boronnitride have superior properties. These include a wider band gap and greater mobility. Diamond and cBN are superior materials for extreme electronics.
Due to the high transmittance and hardness of the cubic-boron film, which is approximately 200 nm, and its ability to cover the entire range of wavelengths, including ultraviolet, this coating can be used as a surface coat for certain optical components.

Boron Nitride Powder Properties
Boron Nitride is resistant to corrosion by chemicals and mineral acids. It is also not affected by water and mineral acid. The boron and nitrogen bond is broken by hot concentrated alkali. Boron Nitride begins to oxidize at temperatures above 1200degC. It decomposes around 2700degC in vacuum. Boron Nitride is slightly soluble when heated acid is used, but insoluble with cold water.Most properties of boron materials are better than those of carbon materials. The following properties are found in hexagonal boron Nitride: Low friction coefficient; good high temperature stability; good thermal shock resistance; high strength; high thermal conductivity.

Boron nitride Powder Applications
Cubic-boron nitride has an excellent heat resistance in addition to its excellent wear resistance. It can cut heat resistant steel, ferroalloys and hardened metals. At a relatively high temperature, it can cut Si-Al and Si-Cr alloys and chilled rolls with high hardness.It is a semiconductor material with a wide band-gap (band-gap of 6.4 eV).
