What’s the difference between Hexagonal Boron Nitride (Cubic Noron Nitride)?
Boron nitride It is composed of both nitrogen atoms as well as boron atoms. It has a chemical composition of 43.6% Boron and 56.4% Nitrogen. There are four variations: hexagonal, cubic, rhombohedral and cubic boron nutrides (HBN), and wurtzite boronboronide (WBN). The most common are cubic boron nutride and hexagonalboron. Boron nitride has a wide range of applications, including in refractory material, semiconductor solid phase doping sources and structural materials for atomic stacks. It is also used to protect against neutron radiation, mold release agents, high-temperature oil lubricants, and rocket engine components. The fibers made with boron nutride can be used inorganically as synthetic engineering materials. This is a common use in the aerospace and defense sectors. CBN can also serve as high-speed cutting tools and deep well drill bits.

What is the main difference between hexagonal boron Nitride and cubic?

Hexagonal Boron Nitride:
Hexagonal Boron Nitride (similar to graphite and also known as graphite-boron nitride or white graphite). Relative density 2.25 Mohs hardness around 2. It is a white, powdery substance that melts under high pressure at around 3000°C. Good electrical insulation, thermal conductivity. Corrosion resistance. It does not react with alkali, acid or water at room temperature. It reacts with hot concentrated, molten alkali or hot chlorine gas. Can withstand temperatures of 2000°C. Can withdraw electrons well. You can get it by heating borax and ammonium chlorineide in a stream ammonia.
BN is an isoelectronic material, as graphite and graphite. It is commonly known as white Graphite. It exhibits a similar structure to graphite and has good lubricity. The shaped products are chemically stable, chemically inert to all the molten metals and easy to machine. Its melting point is 3000degC at nitrogen pressure. Under atmospheric pressure it sublimates to 2500degC. Its theoretical density of 2.29 grams per cubic cmimeter. It has a mohs hardness level of 2, an anti-oxidation temp of 900°C, and high temperature resistance of 2000°C. It can be used in nitrogen or argon environments up to 2700°C.

Cubic Boron Nitride
Cubic boron-nitride (diamond form). For black or brown-colored granular crystals. Relative density 3.48 Melting point 3000 . The hardness of the material is comparable to diamond. It is more stable than diamond at high temperatures. You can easily synthesize nitrogen or boron at high temperatures and pressure.
Boron nitride in cubic structure: The molecular formula of BN is Boron Nitride. Because its crystal structure is almost identical to that of diamond (HV72000-98000 MPa), it is frequently used as an abrasive or tool material. R.H. Wintorf from the United States was the first to develop the cube in 1957. Yanshan University synthesized a new material made of cubic boron nutride with a nano-twin design in 2013. The new material boasts a wide range of exceptional characteristics. It is harder than single crystal diamond, tougher than commercial cemented carbide, and has an oxidation temperature higher than single crystal cubic boron nutride. It will likely be used as a tool material in the steel materials processing industry. Has broad application prospects.

The physical structure of hexagonal boron nuitride and cubic boron is very different. The crystal form cubic boron is more wear-resistant and resistant to pressure and can be used in cutting instruments. It comes at a relatively low price. The idea of stealing is that it’s sold at a low cost. The main chemical composition of this type of coating is also made up of boron Nitride, but the actual nonstick effect of aluminum isn’t good.
Hexagonal Boron Nitride is another form of boron. This crystal form is super lubricating, resistant to high temperature and non-wetting. It is highly preferred for coatings with high temperature non-stick aluminum, but the price is very high. This boron Nitride coating has the best nonstick aluminum effect.
