Boron Nitride Sheet Advantages & Applications:
Boron Nitride ceramic from Edgetech Industries Ceramics Division can withstand high temperatures in a high vacuum environment, plus it has excellent corrosion resistance and electrical resistance.
-Low wettability to molten metal
-Relatively high thermal conductivity with low thermal expansion
-Relatively high thermal shock resistance
-Extremely high working temperature with proper inert gas protection
Based on the above properties, Boron Nitride Sheet is an ideal choice in a wide range of industries, such as:
-Electric insulators in vacuum system
-Insulators for high-temperature furnace
-Spacers for glass melting
-Boron Nitride parts for ion injection equipment
Packing
As a ceramic material, BN is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Sheets are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
