Boron nitride nozzles have excellent wear resistance, high-temperature resistance, and corrosion resistance, and play an important role in powder metallurgy, abrasive jetting, burners, and coating spraying.

High-purity boron nitride nozzles could withstand higher temperatures in a vacuum than lower-purity boron nitride nozzles. Due to the low wettability with metals, boron nitride is an ideal material to handle molten metals, especially for high-purity material metals in a vacuum.

In recent years, the additive manufacturing industry based on 3D printing technology has developed rapidly, and ceramics are increasingly used in special and complex parts. The basic raw material of metal 3D printing technology is a metal powder with high sphericity and narrow particle size distribution. The basic process for preparing and producing this powder is to melt a metal alloy and flow it through a nozzle. At the nozzle outlet, high-pressure airflow is used to atomize the metallic liquid while cooling it into spherical particles. Therefore, the nozzle material needs to have properties such as high-temperature resistance, thermal shock resistance, finishing ability, and resistance to liquid metal corrosion. We offer metal atomization powder nozzles and flow nozzles for 3D printing or powder metallurgy.

-Abrasive nozzle: used in abrasive blasting equipment, surface treatment, and cleaning applications, it can provide long-term and stable spraying effects in high-speed, high-pressure, and high-concentration abrasive flows.

-Burner nozzle: it can be used for injection and regulation of high-temperature burners. Boron nitride ceramic nozzles can provide stable combustion injection, and improve combustion efficiency and stability.

-Air atomizing nozzle: Boron nitride ceramic nozzles are widely used in the fields of coating, spraying, and atomization, they can be used for spraying high-temperature spray liquids, powders, and aerosols.


As a ceramic material, boron nitride is quite fragile in a lot of cases. Our Hot-Pressed Boron Nitride nozzle is carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used for BN products, vacuum packing is also engaged for some of the parts.
