Boron Nitride Rod 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 Rod is an ideal choice in a wide range of industries, such as:

-Evaporator Boats

-Nozzles for nonferrous metals metallurgy industry

-Electric insulators in the vacuum system

-Insulators for high-temperature furnace

Packing

As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride Rod 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.
