Saint-Gobain Ceramics

Combat AX products hot-pressed 99.7+%-purity hexagonal boron nitride (hBN) exhibits exceptionally high thermal-shock resistance, electrical insulation over 1800°C and high thermal conductivity. AX05 is the material of choice in kiln furniture and furnace construction. AX15 permits flow of process gases where outgassing is required, making it particularly suitable for direct-contact, high-temperature environments such as crucibles, plates, setters, supports and muffles for aluminum nitride, silicon nitride and SiAION ceramic sintering. The AX family of boron nitride products can be easily machined into intricate shapes with tight tolerances using standard machining tools.
