- Development history of boron nitride Boron nitride (BN) compound was first discovered in 1842. Research on BN materials began after the end of World War II, but the ceramic was not officially developed until 1955 when...More>>
- One of the main interests of ceramic 3D printing in aerospace field is to use this technology to manufacture ceramic matrix composites, which have obvious performance advantages over superalloys and much lower density. For...More>>
- 1. Travel in space needs high efficient thrusters When the satellite is in operation in space, it will gradually reduce its speed due to the resistance of a small amount of gas in orbit. As a result, there will be...More>>

Introduction of ways to make BN powder 07/20/2021High temperature and high-pressure synthesis In 1957, Wentorf synthesized cubic BN for the first time. When the temperature is close to or higher than 1700 ℃ and the minimum pressure is 11-12gpa, pure...More>>
- Graphite has sublattice symmetry (2 C in a unit cell) which protects the Dirac point in its band structure, and thus is gapless. On the other hand, in BN the sublattice symmetry is broken (1B and 1N in a unit cell), which...More>>

Property of hexagonal boron nitride material 07/20/2021Hexagonal boron nitride (hBN) can be prepared by melting B2O3 with NH4Cl or burning boron in NH3. Generally, Boron nitride has graphite-like layered structure. It is a white powder with loose, lubricating, moisture...More>>
- Boron nitride (BN) is a crystal composed of nitrogen and boron atoms. It has four different variants: hexagonal boron nitride (h-BN), rhombohedral boron nitride (r-BN), cubic boron nitride (c-BN) and wurtzite boron...More>>
