Precision Machining 99 Al2O3 Tube Alumina Ceramic

Precision Machining 99 Al2O3 Tube Alumina Ceramic

A simple 99% alumina ceramic tube is a cylindrical piece of material that is made primarily from aluminum oxide, which is a compound of aluminum and oxygen. Here are some key characteristics of such a tube.

Composition: It is composed of 99% aluminum oxide (Al2O3), which is a white, crystalline substance known for its hardness and chemical stability.

Properties:

High Purity: The high alumina content ensures purity, which contributes to its strength and resistance to chemical reactions.

Thermal Stability: It can withstand high temperatures without significant degradation, making it suitable for use in high-temperature environments.

Corrosion Resistance: Alumina is resistant to most acids and alkalis, making the tube suitable for corrosive environments.

Electrical Insulation: It is a good electrical insulator, which is useful in electrical applications.

Applications:

Industrial Furnaces: Due to its high-temperature resistance, it is used in furnaces and kilns.

Chemical Processing: Its chemical inertness makes it ideal for use in chemical processing equipment.

Heat Exchangers: It can be used in heat exchangers due to its thermal stability and resistance to corrosion.

Ceramic Filters: The tube can be used as a filter medium in various industrial processes.

Manufacturing: Alumina ceramic tubes are typically manufactured using processes such as slip casting, extrusion, or pressing, 

followed by high-temperature sintering to achieve the desired properties.

Dimensions: They can be made in various sizes and shapes, depending on the application requirements.

Surface Finish: The surface of the tube is usually smooth, which is beneficial for applications where flow or heat transfer is critical.

Handling: While strong, alumina ceramic tubes can be brittle and should be handled with care to avoid breakage.

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

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
