Specification of China Factory High Temperature Refractory Aln Ceramic Aluminum Nitride Tube

China factories make high temperature refractory AlN ceramic tubes. Aluminum nitride ceramic is a special material. It handles extreme heat very well. It also moves heat fast. This is thermal conductivity. Aluminum nitride has high thermal conductivity. Electrical insulation is another key point. It stops electricity flow. These tubes are strong mechanically. They resist wear over time. Chemical stability matters too. AlN tubes do not react with many substances. This keeps them safe in harsh places.

People use these tubes in tough jobs. Semiconductor manufacturing needs them. High temperature furnaces use them as parts. Thermal management systems rely on AlN tubes. They are good for holding hot things. They work well as protective sleeves. Electrical insulators in hot spots use them. Laser applications find them useful. Crucibles for melting might use AlN.

The tubes come in various sizes. Factories control the sizes carefully. Wall thickness can be different. Lengths can be made to order. The outside diameter and inside diameter are important. These sizes must be exact for the job. China factories use modern methods. They press the powder into shapes. Then they fire it very hot. This sintering makes the ceramic dense. A dense structure gives better strength. It also improves thermal performance.

Key specifications define quality. Thermal conductivity is often 170-180 W/mK. This is very high for a ceramic. Electrical resistivity is high too. It might be over 10^14 ohm-cm. The maximum use temperature is high. It can be around 1800°C in air. Purity is critical. Good tubes have over 99% aluminum nitride. Fewer impurities mean better performance. Flexural strength shows how tough it is. Values around 300-400 MPa are common. Density is usually high. It might be near 3.3 g/cm³. Surface finish can be smooth. This depends on the grinding after firing.

Applications of China Factory High Temperature Refractory Aln Ceramic Aluminum Nitride Tube

China factory high temperature refractory AlN ceramic aluminum nitride tube handles extreme heat well. This makes it vital for demanding industries. Aluminum nitride offers excellent thermal conductivity. It moves heat efficiently. The material also provides strong electrical insulation. This combination is rare. AlN tubes withstand temperatures far beyond many metals or plastics. They resist thermal shock too. Sudden temperature changes cause less cracking. Chemical resistance is another key feature. AlN tubes work well in corrosive settings. They show little reaction to many acids and bases.

These properties make AlN tubes essential in semiconductor manufacturing. They transport hot gases safely inside processing chambers. The tubes protect sensitive electronic components. Their insulation prevents electrical interference. LED production relies heavily on AlN tubes too. They form the core parts of high-power LED assemblies. Efficient heat dissipation extends LED lifespan. It keeps brightness consistent. Thermal management systems use AlN tubes actively. They move heat away from critical spots in power electronics. This prevents overheating failures.

Research labs and industrial furnaces benefit from AlN tubes. Scientists use them for high-temperature experiments. The tubes hold samples securely under intense heat. Industrial furnaces employ them as protective sheaths. They shield thermocouples and sensors from direct flame contact. This ensures accurate temperature readings. Harsh chemical processes often require AlN tubes. They carry aggressive substances without degrading. This reliability reduces equipment downtime. AlN tubes maintain integrity in vacuum conditions. They perform reliably in controlled atmospheres. Their mechanical strength supports structural use.

Choosing the right AlN tube matters. Consider the operating temperature range first. Match it to your specific process heat levels. Check the required chemical resistance. Ensure it suits the substances involved. Dimensions are critical for proper fit. Verify inner diameter, outer diameter, and length. Surface finish might affect performance. Smoother finishes sometimes work better. Discuss your exact needs with the supplier. They can recommend the best specifications.
