Boron Nitride has unsurpassed thermal stability and is stable at temperatures up to 1000 C in air, 1400 in vacuum, and 2800 C in an inert atmosphere. It is also self-lubricating, so it does not require the use of gas or water molecules trapped between its layers. Because of this, boron nitride ceramic parts can be used in a vacuum, which is essential for aerospace applications.
Boron Nitride Properties
To make solid shapes, hBN powders and binders are hot-pressed in billets up to 490mm x 490mm x 410mm at pressures up to 2000 psi and temperatures up to 2000°C. This process forms a material that is dense and easily machined and ready to use. It is available in virtually any custom shape that can be machined and has unique characteristics and physical properties which make it valuable for solving tough problems in a wide range of industrial applications.
Excellent thermal shock resistance
High electrical resistivity – excluding aerosols, paints, and ZSBN
