Product Description

BN Ceramic/Boron Nitride Coatings For The Metal Processing Market

Specifications

BN99 ; BN+Ca ; BN+Si ; BN+Al2O3 ; BN+SiC ; BN+ZrO2 ; BN+AlN

Advantage

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
