The Difference Between Hexagonal Boron Nitride And 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 in organic synthetic engineering materials. This is widely used 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 and cubic-boron Nitride?

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 at room temperatures with acid, alkali, or water. It reacts with hot concentrated, molten, and hot chlorine gas. Can withstand temperatures of 2000°C. Can withdraw electrons well. It is possible to obtain it by heating borax chloride and ammonium chloride in an ammonia stream.
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 excellent lubricity. The shaped products are chemically stable, chemically inert to all the molten metals and easy to machine. Its melting point is 3000 degrees Celsius under nitrogen pressure. Under atmospheric pressure it sublimates at 2500 degrees Celsius. It has a theoretical density of 2.29 grams per cubic cm. It has a mohs hardness level of 2, an anti-oxidation temp of 900°C, and high temperature resistance of 2000°C. The melting point in nitrogen and argon is 3000°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. This 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. Cubic boron is a crystal form that is resistant to pressure and wear. It is commonly used in cutting instruments. The price is very low. 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 non-stick effects of aluminum are not as good.
Hexagonal Boron Nitride is another form of boron. This crystal form is super lubricating, resistant to high temperatures, and non-wetting. It is the most preferred material for high temperature nonstick aluminum coatings. The price is also quite high. This boron Nitride coating has the best nonstick aluminum effect.
