The Application of BN Ceramic Nozzle

As a hot-pressed hexagonal material, boron nitride (BN) exhibits a distinctive combination of chemical, electrical, mechanical, and thermal characteristics, making it ideal for demanding high-performance applications. BN ceramic nozzles are widely employed in high-temperature and high-performance industries such as aerospace and semiconductors. In recent years, these components have attracted significant interest owing to their following unique properties:

1.Exceptional Thermal Stability
With melting point of approximately 2900°C, BN ceramic nozzle can be used for temperature 1800 °C and 2100°C separately in high vacuum and inactive gas environment.

2.Thermal Shock Resistance
BN nozzles can withstand rapid temperature changes without cracking. So it can be used in environments with dramatic temperature fluctuations dramatically.

3.Extreme Corrosion Resistance
Boron Nitride ceramic has high resistance to chemical corrosion like acids and alkalis. It can protect the nozzle from the materials it handles to reduce the risk of contamination and extend lifespan.

4.Self-lubricating
BN material is self-lubricating. It can make sure molten materials do not adhere to the nozzle, preventing clogging and ensuring smooth material flow.

5.Electrical Insulation
BN is an excellent electrical insulator, so it is suitable for applications like high voltages or plasma.

Material Property

With exceptional thermal stability, excellent thermal shock resistance, outstanding electrical insulation, chemical inertness, and lubricity, we have developed a new series of nozzles for metal and glass processing, 3D printing, as well as applications in the semiconductor and aerospace industries.

1.Metal and Glass Processing
BN nozzle is widely used in metal casting and glass manufacturing, where it is exposed to molten metals and glass in high temperature. BN’s high wet resistance to molten metals and glass, its chemical inertness guarantees smooth flow and prevent clogging. If you are looking for metal and glass processing nozzle, BN will be a good choice.

2.3D Printing
In metal 3D printing, BN nozzles are used to deliver powdered materials or molten metals. Its thermal stability and low friction properties make sure consistent material flow, reducing wear and tear of equipment and improving print quality.

3.Semiconductor Industry
In semiconductor industry, BN nozzles used in chemical vapor deposition (CVD) and some high-temperature processes. It is suitable to handle reactive gases and ensure precise deposition as it won’t produce chemical reaction even under extreme conditions.

4.Aerospace Industry
BN nozzle is used in rocket engines and thrusters. It has the ability to withstand extreme temperatures and resist thermal shock, which makes it an ideal use for directing high-velocity exhaust gases.

The BN nozzle’s applications in metal and glass processing, 3D printing, Semiconductor and aerospace demonstrate its versatility and reliability. With its numerous advantages, BN nozzle continues to be a preferred choice for high-performance applications.
