Alumina, or aluminum oxide, with a molecular weight of 102, is the major source of aluminum in nature. Alumina has very high melting point, which is 2,072 °C and it is extremely hard. Alumina ceramic is the common technical ceramic material and a relatively traditional material. High purity alumina ceramics as a fine ceramic material is widely used in a lot of industries. This material has superb performances in electrical insulation, high chemical resistance and low thermal expansion. Alumina tubes are used for industrial furnace and thermal couple protector. High purity alumina materials are excellent for making parts for CVD, ion implants, photolithography, and semiconductor parts. In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles and insulators. Compared with metals, alumina ceramic material is extremely hard, making it an ideal material for abrasive, grinding media. Alumina mortars and pestles are widely used in laboratories for grinding hard materials.

Alumina is a well-known and commonly used precision ceramic material. It has the same sintered crystals as sapphire and ruby. For decades, it was once used in electrical components because of its high electrical insulation. It is widely used in mechanical parts because of its high strength, high corrosion resistance and high wear resistance.

Main Features:

1. High hardness

2. High heat resistance

3. Good wear resistance

4. High electrical resistivity

5. High corrosion resistance

Technical Parameters

Ceramic Substrate

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
