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.

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 soluble only in warm acid, but insoluble in cold waters.

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 thermal shock resistance; high strength; high thermal conductivity; low expansion coefficient; high resistivity.

The most common boron system is hexagonal, with a graphite structure. There are many other crystal systems of boron, such as rhombohedral, cubic, and wurtzite boron.

Boron nitride Powder Applications

Cubic-boron nitride has excellent heat resistance in addition to its excellent wear resistance. It can cut heat resistant steels, ferroalloys or hardened steels. 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 (6.4 eV). Cubic-boron nitride exhibits high thermal conductivity, good resistivity, good mobility, low dielectric constant and high breakdown field. 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 its high hardness, cubic-boron film is suitable for optical applications. Its high transmittance over the entire range of wavelengths from ultraviolet (approximately at 200 nm), to far infrared makes it a suitable surface coating on some optical components.
