The first application of hexagonal boron nitride was as a high-temperature lubricant. 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 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 also amorphous forms. In addition to hexagonal boron, nitride crystals include: rhombohedral, Cubic, and Wurtzite types.
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 steel. 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). Cubic-boron nitride exhibits high thermal conductivity, good resistivity, high mobility and low dielectric constant. 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 and high transmittance across the entire spectrum of wavelengths from ultraviolet (approximately 200 nm to far infrared), it is suitable for optical applications.
