Material Advantages of Boron Nitride

What is Boron Nitride?

Boron Nitride is an advanced synthetic ceramic material in solid and powder form. Its unique properties – from high heat capacity and outstanding thermal conductivity to easy machinability, lubricity, low dielectric constant, and superior dielectric strength – make boron nitride a truly outstanding material. In its solid form, boron nitride is often referred to as "white graphite" because it has a microstructure similar to that of graphite. However, unlike graphite, boron nitride is an excellent electrical insulator with a higher oxidation temperature. It offers high thermal conductivity and good thermal shock resistance and can be easily machined to close tolerances in virtually any shape. After machining, it is ready for use without additional heat treating or firing operations.

 

Material Advantages of Boron Nitride

To make solid shapes, hexagonal Boron Nitride (hBN) powders and binders are hot-pressed into billets up to 490mm x 490mm x 410mm at pressures up to 2000 psi and temperatures up to 2000°C. This process forms a dense, easily machined material and is ready to use. It is available in virtually any custom shape that can be machined and has unique characteristics and physical properties, making it valuable for solving tough problems in various industrial applications. Excellent thermal shock resistance, High electrical resistivity – excluding aerosols, paints, and ZSBN grade, Anisotropic (thermal conductance differs between parallel and perpendicular planes to pressing direction), High dielectric breakdown strength, >40 KV/mm.

 

General Properties Boron Nitride

Boron Nitride is an excellent choice for all but the most severe refractory applications. It is a high-performance material with a glassy B2O3 binder that creates a hard, dense, fully machinable material. Grade A is the oldest form of hot-pressed Boron Nitride. Specified into applications 50+ years ago, Grade A still finds a substantial replacement business as relatively high-temperature insulators in legacy semiconductor equipment and defense applications. Components can be produced up to 410mm x 495mm x 245mm. However, its B2O3 binder is hygroscopic, and care must be taken to ensure components are isolated from moisture during storage and use. Precision Ceramics uses many packaging methods to maintain the high quality of its machined components.
