Advantages and applications of boron nitride gasket sealing elements:

Edgetech Industries’ Ceramics Division’s boron nitride ceramics can withstand the high temperatures found in high vacuum environments and offer excellent corrosion resistance and electrical resistance.

-Low wettability to molten metal

-Relatively high thermal conductivity and low thermal expansion

-High thermal shock resistance

-Extremely high operating temperatures and appropriate inert gas protection

Based on the above characteristics, boron nitride gasket sealing elements are an ideal choice for many industries, such as:

-Insulators for high-temperature furnaces

-High voltage equipment feed

-Gasket for glass melting

-Boron nitride parts for ion implantation equipment

Packing

As a ceramic material, boron nitride is very fragile in many situations. Our hot-pressed boron nitride gasket sealing elements are carefully processed to minimize damage during storage and shipping. BN products use appropriate outer boxes and inner cushioning materials, and some components are also vacuum-packed.
