BN99 ; BN+Ca ; BN+Si ; BN+Al2O3 ; BN+SiC ; BN+ZrO2 ; BN+AlN
Non-toxic
High purity
Low density
Chemically inert
Non-porous
One of the highest dielectric strengths known
Good thermal conductivity
Tensile strength increases with temperature
Excellent thermal shock resistance
High oxidation resistance
Negligible outgassing
Advantageous anisotropy (electrical, mechanical, and thermal)
It is produced in a hot pressed form and the resulting material properties are anisotropic relative to the press direction. In fact, the material properties can vary considerably depending on the direction or the grade of the material. Futhermore, it is easily machined into complex shapes using standard carbide tooling. The operation temperatures range from 900°C for oxidizing environments to 2200°C for inert environments.TECHNICAL PROPERTIES
