Boron Nitride Plate / Sheet
We provide standard products & tailor-made products for hot-pressed boron nitride plate & sheet. Except for pure BN99 plates & sheets, we also supply BN composites with silicon carbide, calcium borate, aluminum nitride and zirconia, to fulfill various of demand for the customers. Check the boron nitride specifications for our pure BN99 and zirconia composite material ZSBN.
The raw boron nitride blank we can provide is as large as 16″ x 12″ x 12″. It could be cut into sheets and plates, for customer to make further machining. While *Enhanced boron nitride sheets are usually available within 12″x12″x12″.

Boron Nitride Plate & Sheet Advantages & Applications:
Boron Nitride ceramic from Edgetech Industries Ceramics Division can withstand high temperature in the 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 (>3000C has been recorded).
Based on the above properties, Boron Nitride Plate & 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
As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Plate & Sheet is 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.
