The Difference Between Hexagonal Boron Nitride and Cubic Noron Nitride


There is a difference between Cubic Noron Nitride (hexagonal Boron Nitride) and Cubic Noron Nitride (cubic noron).


Boron nitride



It is composed of both nitrogen and boron elements. This crystal contains 43.6% boron, 56.4% nitrogen and four variations: hexagonal and cubic boron nutrides (HBN), rhombohedral and cubic boron triides (RBN), and wurtzite Nitroboronide (WBN). The most common are cubic and hexagonal boron nutrides. Boron Nitride is used primarily in refractory material, semiconductor solid phase doping sources and structural materials of Atomic stacks. The fibers made with boron nutride can be used for inorganic, synthetic engineering purposes and are popular in defense and aerospace industries. CBN can be used in high-speed cutters and as drill bits for deep wells.


What’s the difference between cubic and hexagonal boron nutride?


Hexagonal Boron Nitride:


Hexagonal Boron Nitride (similar graphite; also called graphite and graphite bi-nitride, or simply graphite). Ratio density: 2.25 Mohs hardness around 2. The powder melts at around 3000 degrees Celsius under high pressure. Good electrical insulation, thermal conductivity. Corrosion resistance. It does not react to water, acid or alkali at ambient temperature. It reacts with hot concentrated and molten alkali, as well hot chlorin gas. It can withstand temperatures up to 2000 degrees Celsius. Can withdraw electrons well. This can be achieved by heating ammonia chloride and borax together in a stream.

BN and graphite both are isoelectronic substances. It’s also called white graphite. This layered material, which is similar to graphite has excellent lubricity and electrical insulation as well as thermal conductivity, chemical resistance and neutron absorption. The shaped product is chemically stable, inert and resistant to all molten metallics. It can also be easily machined and has high moisture resistance. Under nitrogen pressure it melts to 3000°C and then sublimates to 2500°C at atmospheric pressure. It has a theoretical density of 2.29 grams per cubic cm. Mohs hardness 2; anti-oxidation temperature 900°C, high resistance 2000°C. The melting point for nitrogen and argon are 3000°C and 2700°C respectively.


Cubic Boron Nitride


Cubic Boron Nitride (diamond form). You can use granular black crystals or brown. Relationship density 3.48 Melting point 3000 . This hardness is the same as that of diamond. It is more stable than diamond at high temperatures. You can easily synthesize nitrogen or boron at high temperatures.

Boron nitride has a cubic structure. This molecular formula, BN, is the same as that of diamond. Because its crystal structure is almost identical to that of diamond (HV72000-98000MPa), it’s often used in abrasives and other tool materials. R.H. Wintorf from the United States was the first to develop the cube in 1957. Yanshan University synthesized a cubic boron-nitride material with a nanotwin structure. It has many outstanding properties. It has higher hardness than diamond single crystals and toughness than commercial cemented carbide. Additionally, its oxidation resistance temperature exceeds that of cubic-boron nitride single cristal. It will be used as a cutting-edge tool in the steel materials processing industry. Has broad application prospects.

Cubic boron Nitride and hexagonal Boron Nitride are fundamentally different because of the differences in their physical structure. Cubic boron nitride crystal is more wear-resistant than hexagonal boron, so it is commonly used for cutting. This is a relatively affordable price. The idea of theft is that it’s sold at a relatively low price. The main chemical composition for this type of coating also includes boron trioxide. However, it does not have the same non-sticky effect as aluminum.

The hexagonal form of boron is also a crystal. This crystal form boron is superlubricating and resistant to heat. It also resists metal wetting. The preferred choice for coatings with high-temperature non-stick aluminum, but the cost is prohibitive. This is the boron-nitride coated that has the most non-sticky aluminum coatings on market.
