Applications of High purity large diameter alumina ceramic tube 99% al2o3 for pipe tube furnace

High purity large diameter alumina ceramic tubes, made from 99% Al2O3, are essential in demanding high-temperature settings. These tubes are incredibly tough and resist heat extremely well. This makes them perfect for lining tube furnaces. They create a protective barrier inside the furnace. This barrier shields the outer furnace shell from intense heat. It keeps the furnace structure safe and working longer. These ceramic tubes also handle corrosive chemicals effectively. They won’t easily break down when exposed to aggressive gases or molten materials. This chemical resistance is a major advantage.

These tubes are widely used as thermocouple protection sheaths. Thermocouples measure temperature inside furnaces. The ceramic sheath protects the delicate thermocouple wires. It allows accurate temperature readings even in very harsh conditions. Another key use is as sample holders or boats. They securely hold materials during high-temperature processing. This is common in labs and industries like semiconductors. The tubes ensure samples are processed uniformly without contamination.

Large diameter versions are excellent for gas inlet or outlet tubes. They safely guide gases into or out of the hot furnace zone. Their purity means they won’t react with the gases or introduce impurities. This is vital for processes needing clean environments. Alumina ceramic tubes also act as radiation baffles. They help control heat flow inside the furnace. This improves temperature uniformity and energy efficiency. Their smooth surface makes them easy to clean and reuse. They last a long time, reducing the need for frequent replacements. This saves money and downtime.
