aircleaningceramic

BN is a hot-pressed hexagonal boron nitride with a unique combination of chemical, electrical, mechanical, and thermal properties. It is suitable for a range of applications where high performance is required. BN ceramic nozzle is used in various high-temperature and high-performance industries like aerospace and semiconductor, which has gained much attention in recent years due to its unique properties below:1. Exceptional Thermal StabilityWith a melting point of approximately 2900°C, BN ceramic nozzle can be used for temperatures of 1800 degrees and 2100 degrees separately in high vacuum and inactive gas environments.2. Thermal Shock ResistanceBN nozzles can withstand rapid temperature changes without cracking. So it can be used in places where temperatures can fluctuate dramatically.3. Extreme Corrosion ResistanceBoron 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-lubricatingBN material is self-lubricating. It ensures molten materials do not adhere to the nozzle, preventing clogging and ensuring smooth material flow.5. Electrical InsulationBN is an excellent electrical insulator, making it suitable for applications like high voltages or plasma.Material PropertyMaterial CompositionBN+ZrO299 BNDensity2.8g/cm2-2.9g/m32g/cmColorWhite GraphiteWhiteBending Strength90MPa35MPaCompressive Strength220MPa85MPaThermal Conductivity30W/(m.k)40W/(m.k)Thermal Expansion Coefficient (20-1000°C)3.5 10-6/K1.8 10-6/KMax working temperatureIn Inactive Gas 1800 °CIn Inactive Gas 2100 °CIn High Vacuum 1800 °CIn High Vacuum 1800 °CIn Atmosphere 900 °CIn Atmosphere 900 °CWith properties of exceptional thermal stability, excellent thermal shock resistance, outstanding electrical insulation, chemical inertness, and lubricity, we have developed a series of new products for metal and glass processing nozzles, nozzles for 3D printing, and semiconductor and aerospace industries.1. Metal and Glass ProcessingBN nozzle is widely used in metal casting and glass manufacturing, where it is exposed to molten metals and glass at high temperatures. BN’s high wet resistance to molten metals and glass, no reaction to chemical material guarantees smooth flow and prevents clogging. If you are looking for metal and glass processing nozzles, BN will be a good choice.2. 3D PrintingIn metal 3D printing, BN nozzles are used to deliver powdered materials or molten metals. Its thermal stability and low friction properties ensure consistent material flow, reducing wear and tear of equipment and improving print quality.3. Semiconductor IndustryIn the semiconductor industry, BN nozzles are 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 reactions even under extreme conditions.4. Aerospace IndustryBN nozzle is used in rocket engines and thrusters. It has the ability to withstand extreme temperatures and resist thermal shock, which makes it ideal 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, the BN nozzle continues to be a preferred choice for high-performance applications.
