Boron Nitride Ceramic Nozzles

Boron Nitride Ceramic Nozzle is a high-performance ceramic component manufactured from high-purity boron nitride materials. It combines excellent thermal conductivity, low thermal expansion, superior thermal shock resistance, and outstanding high-temperature stability, making it suitable for demanding industrial environments.

Unlike traditional ceramic nozzles, boron nitride nozzles offer excellent non-wetting properties with molten metals and glass materials, reducing material adhesion and improving production efficiency. They can maintain stable performance under repeated heating and cooling cycles.

With a thermal conductivity of 180-220W/(m·K) and a low thermal expansion coefficient of 4.5×10⁻⁶/℃, Boron Nitride Ceramic Nozzles are widely used in high-temperature melting systems, industrial lubrication and release applications, and high-temperature electrical insulation components.
