Boron nitride ceramic crucible with lid

Commonly used types of boron nitride are cubic boron nitride (C-BN) and hexagonal boron nitride (P-BN). Among them, boron nitride crucibles are usually composed of P-BN. P-BN ceramics have good heat resistance, thermal stability, thermal conductivity, and high-temperature dielectric strength, which is an ideal heat dissipation material and high-temperature insulation material.

Due to its excellent chemical stability, P-BN can resist the erosion of most molten metals, and is best suited for harsh environmental conditions, such as semiconductor manufacturing processes, due to the above-mentioned high-temperature insulation properties, high thermal conductivity, and low thermal expansion properties. Depending on the material used. P-BN crucibles are commonly used in the smelting of metals and semiconductors. It can be used at temperatures up to 1800°C under vacuum and up to 2100°C under inert gas protection.
