Boron Nitride Ceramic components, BN

Boron nitride ceramic products must be vacuum-sealed because they are highly sensitive to oxygen and moisture in the environment. When exposed to air, boron nitride ceramics readily absorb moisture, which can lead to a degradation of their material properties. Additionally, the surface of this ceramic is susceptible to contamination by fine particles, dust, or other pollutants. These contaminants can adversely affect the material's electrical insulation properties and other physical characteristics. The performance and applications of boron nitride ceramics are as follows:
