What is BN? Is Boron Nitride Hard?

What’s Boron Nitride?

Boron nitride

This is a heat and chemically-resistant refractory mixture of boron, nitrogen with the chemical name BN.

Which chemical property is Boron Nitride’s?

This is a deceptive empirical formula for the boron nutride (BN). BN differs from diatomic molecules, such as hydrogen chloride and carbon monoxide. Contrary to popular belief, BN has much in common with carbon. The representation of carbon (a single atom) is inaccurate.

Is Boron Nitride (BN) Hard?

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


Has the same hexagonal shape as graphite. It also has similar softness properties and lubricating characteristics. You can make hBN in graphene sheets, which are able to form nanotubes.

Cubic boron (cBN), however, has electronic properties that are very similar to diamond. While it isn’t difficult to make, it is chemically as well as thermally more stable. It’s also much easier to create. It can be made at higher temperatures than diamond and is therefore more wear-resistant. An amorphous version (aBN), is available, which is the same as amorphous carbon. (See below).

BN is a synthetic material. However, reports indicate that there may be naturally-occurring deposits. The first attempts at making pure BN are back in the early 20th-century. However, commercially available forms of BN have not been manufactured since the 1970s. According to the 1958 Carborundum Company patent (Lewiston New York), the scientist created BN by heating boric acids (H3BO3) with metal salts oxyacids (such phosphate) and ammonia. It is then shaped. Then, mix it up and compress it to form.

Today similar techniques are used. They use diboron Trioxide (B2O3) and H3BO3 to start with, while urea or ammonia serve as nitrogen sources. Each synthesis method produces a slightly impure amount of aBN. The aBN is heated at higher temperatures to convert it into hBN. Similar to the preparation of synthetic diamonds, hBN can be converted into cBN by heating at high temperatures and pressure.

Boron Nitride applications

Boron Nitride can be an industrial chemical used extensively in today’s modern industry.


Hexagonalboron nitride can be used as a lubricant in paint, cosmetics pencil lead and dental cement. Its lubricating capabilities can still play an important role in vacuum systems, even if there is no water or gas in the compound layers.

BN offers significantly higher chemical stability and conductivity than graphite.

Equipment under high-temperature environment

The compound’s exceptional heat resistance means it is well-suited for applications that involve extremely high temperatures. Hexagonalboron nitride can be used to enhance the lubricating qualities of ceramics, rubber and plastics.

In plastics, BN components may provide lower thermal expansion. This component can be integrated in semiconductor substrates or microwave oven windows.

Because of its thermochemical capabilities, Boron nitride makes a great ingredient in reaction vessels or crucibles.

Semiconductor Industry

Boron nitride’s bandgap is 4.5-6.4 eV. This makes it an ideal wide-bandgap material for semiconductors. Due to its thermal and dielectric qualities, it can be used as a substrate to develop metal oxide semiconductor field effect transistors (MOSFET), and other semiconductors.

Grinder and cutter tools

Because of its unique physical properties, cubic boron is used to abrase nickel, iron, or other alloys that do not suit diamond. The cubic boron butride version is used for cutting and grinding.

Boron Nitride price

Boron Nitride’s price can vary according to weather and marketing costs. It is common for 1.5 lbs to cost more than $69 You can contact us for the current Boron nitride price. We will send you a pricelist tailored to your needs.
