High Temperature Resistant 99 Ceramic Alumina Tube For Furnace

High Temperature Resistant 99 Ceramic Alumina Tube For Furnace

Alumina ceramic tubes for furnaces are highly regarded for their exceptional properties, including high thermal stability, mechanical strength, and electrical insulation. These tubes, made from aluminium oxide (Al2O3), can withstand temperatures up to 1650°C, making them ideal for use in high-temperature environments such as industrial furnaces and thermocouple protectors. They are also valued for their low thermal expansion, chemical inertness, and resistance to wear and corrosion. Alumina ceramic tubes are used in various applications, including semiconductor manufacturing equipment, insulation, wear parts, and as components in general machinery and hydraulic systems. Their high purity levels (ranging from 99% to 99.8%) contribute to their excellent electrical insulation properties and chemical resistance. These tubes are carefully packaged to prevent damage during storage and transportation, reflecting their importance in a wide array of high-temperature and demanding applications.

Technical Parameters

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
