The main properties of boron nitride ceramics

  1. Mechanical strength: Boron nitride has low mechanical strength, better than graphite at room temperature, but more brittle than oxide ceramics.
  2. Lubricity: Boron nitride powder is a kind of hexagonal crystal, which is a white flake of high-quality material, similar to graphite, commonly known as white graphite, with excellent lubricating properties.
  3. Stability: Boron nitride has no effect on the chemical stability of most metals (such as iron, aluminum ceramics, copper solution, and silicon, GaAs, brass, and cryolite).
  4. Lightweight: Boron nitride ceramic is a kind of lightweight ceramic material. 2.27 g/cm3. 5. Excellent thermal properties: Boron nitride ceramics can be used in an oxidizing atmosphere of about 1000°C and an inert atmosphere of nearly 3000°C, which is higher than the refractory materials of mullite, alumina, and silicon carbide. At the same time, it has high thermal shock resistance at 1500 degrees Celsius, repeated quenching and heating, no cracks, and is very stable.
