Boron Nitride – What are its benefits?

Boron nitride

This chemically resistant boronnitrogen refractory compound can withstand heat or chemicals. The chemical formula to BN.

Which chemical property is Boron Nitride?

This deceptive formula is for the boron nutride (BN). BN does not differ from diatomic molecules such as carbon monoxide and hydrogen chloride. Contrary what many believe, BN is very similar to carbon. This is a misleading representation of carbon, a single element.

Is Boron Nitride (BN) Hard?

BN is similar to carbon in that it can come in many forms. The most stable structure of BN is


The hexagonal structure is the same as graphite. Also, it has the same softness characteristics and lubricating qualities as graphite. You can form hBN with graphene sheets.

Cubic Boron (cBN), however, shares an electronic relationship with diamond. Although it’s not hard to make it, its chemical stability is better. Additionally, it’s much easier to produce. This material can also be produced at higher temperatures that diamonds and it is more resistant to wear. There is an amorphous variant (aBN), which can be made at higher temperatures than diamond and is therefore more wear-resistant. (see below).

Although BN is primarily a synthetic material, some reports suggest that BN could be made from natural resources. Pure BN was made in 20th-century. The commercially viable form of BN has not been made since the 1970s. According to the 1958 Carborundum Company (Lewiston New York patent), the scientist who created BN heated boric acids (H3BO3) in combination with metal salts oxyacids like phosphate and ammonia. This is then moldable. Next, combine it all and form it.

Similar methods are still used in today’s world. Today, they use diboron Trioxide and H3BO3, as well as ammonia (and urea) to provide their nitrogen. Each method results in slightly different amounts of aBN. By heating the hBN at higher temperatures than those used to synthesize it, the hBN can be purified. Like synthetic diamonds are prepared, the hBN needs to be converted into cBN using high pressure and high temperatures.

Boron Nitride application

Boron Nitride, a key industrial chemical in modern industry, can be a useful one.


Hexagonalboron is a good lubricant for paint, pencil lead, and dental cement. Hexagonal boron Nitride’s lubricating properties can be used in vacuum systems even though there are no gas or water in the compound layers.

BN is significantly more chemically stable and conductive than graphite.

Equipment under high-temperature environment

Because of its exceptional heat resistance, the compound is ideal for high-temperature applications. Hexagonalboron is a compound that can improve the lubricating characteristics of ceramics and rubber.

BN elements are useful for plastic’s thermal expansion. You can integrate this component in both semiconductor substrates and microwave oven windows.

Boron nitride is an excellent ingredient in reaction vessels, crucibles and other crucibles because of its thermochemical abilities.

Semiconductor Industry

Boron Nitride’s bandgap ranges from 4.5-6.8 eV. Boron nitride is an excellent wide-bandgap materials for semiconductor applications. Because of its dielectric and thermal properties, it is suitable for use as a substrate in semiconductor development or metal oxide field effects transistors (MOSFET).

How to grind or cut tools

Cubic boron’s unique properties make it a good choice to dissolve nickel, iron or any other alloys which are not compatible with diamond. Cubic boron fluoride is the form used in this polymorph to create cutting and grinding tools.

Boron Nitride price

The price of Boron Nitride will vary depending on the weather and marketing cost. 1.5lbs of Boron Nitride will typically cost $69 more than the regular price. You can reach us for current prices. You will receive a customized pricelist.
