What is Boron Netride?

Boron nitride

It is a heat and chemical-resistant refractory substance of boron, nitrogen with the chemical formula: BN.

What is Boron Nitride’s chemical characteristic?

The empirical formula to make boron-nitride (BN), is misleading. BN is very different to other diatomic molecules, such as hydrogen chloride and carbon monoxide. Contrary to popular belief, BN has a lot of similarities with carbon. The representation of carbon as a single element C is also misleading.

Is Boron Nitride (BN) Hard?

Like carbon, BN can take many forms. The most stable structure is BN.


Has the same hexagonal structure and softness as graphite. You can also make hBN in graphene-like sheets, which can form nanotubes.

Cubic boron nitride, (cBN), is electronically similar to diamond. It isn’t that difficult but is chemically and thermally more stable than diamond. It is also much easier to make. It is not as hard to make than diamond. An amorphous version (aBN) is also available, which is an equivalent to amorphous carb (see below).

BN is a mainly synthetic material. However, there have been reports that BN may be found in natural deposits. The first attempts to make pure BN date back to the early 20th Century, however, it has only been possible to commercially produce it in the last 70 years. The 1958 patent from Carborundum Company (Lewiston), New York, shows how a scientist prepared BN by heating boric acids (H3BO3) with metal salts oxyacids such as phosphate in the presence ammonia. The molded shape. Then, mix it up and shape it.

Today, similar techniques are being used. They use diboron trioxide, H3BO3, or B2O3, as their nitrogen source, and either ammonia (or urea). Each synthesis method produces a bit of impure aBN. The aBN is then purified and converted to hBN by heating at temperatures higher than that used for the synthesis. Similar to the preparation of synthetic diamonds, hBN is also converted into cBN by high pressure at high temperature.

Boron Nitride applications

Boron Nitride can be used extensively in modern industries.


Hexagonalboron nitride can be used as a lubricant in paint, cosmetics pencil lead, dental cement, and other products. Even if there are no water molecules or gas in the compound layer, the lubricating properties of hexagonal boron nitride can still play a part, making it an integral part of the vacuum system.

BN has a significantly higher chemical stability and conductivity than graphite.

Equipment under high-temperature environment

The compound’s exceptional heat resistance makes it suitable for applications that involve extremely high temperatures. Hexagonalboron nitride can be used to improve the lubricating characteristics of rubber, plastics alloys, ceramics, and ceramics.

In the case plastics, the addition of BN components can help to reduce thermal expansion. It can also be embedded into semiconductor substrates or microwave oven windows.

Boron Nitride is a good ingredient in reaction vessels, crucibles and other applications due to its thermochemical capabilities.

Semiconductor Industry

The bandgap ranges between 4.5 and 6.4 eV for boron-nitride, making it an excellent widebandgap semiconductor material. Its thermal and dielectric qualities make it an ideal substrate for developing metal oxide field-effect transistors and semiconductors.

Grinding and cutting tools

Because of its physical properties, cubic boron is a polymorph that can be used to abrase nickel, iron, and other alloys. It’s also suitable for use in situations not suitable for diamonds, such as extremely high temperatures. This form of cubic boron is used in grinding and cutting tools.
