Boron Nitride Ceramic Sleeve for Furnace

Boron nitride ceramic is chemically and has relatively good thermal conductivity, low thermal expansion and microwave clarity. Nitơ boron can be quickly machined as well. Moreover, thủy tinh, salts and the rest of liquid metals are non-wetting. This ensures that neither of these compounds can be moistened, and it is far more immune to chemical assaults.Hexagonal boron nitride (h-BN) performs very well under high heat condition and is effective in the air at temperatures of up to 900 degrees C, in the vacuum at 1,900 degrees C and in the inert environment at 2,000 degrees C. BN is self-lubricating as well,as a result, it does not need the use of molecules of gas or water stuck in its layers. Because of this, in a vacuum, which is important for aerospace applications, boron nitride (BN) can work perfectly.
