High Wear Resistant 99 alumina oxide ceramic corundum tubes pipe

Alumina ceramic tube is a common and important ceramic material, which has a wide range of applications. It not only has excellent physical and chemical properties, but also has strong heat resistance, corrosion resistance and insulation properties, so it is widely used in many industrial and scientific fields. The main component of alumina ceramic tube is alumina (AL2O3), which is a high-purity ceramic material. Alumina has good insulation properties and heat resistance, and can maintain stable performance in high temperature environments. Alumina also has high hardness and abrasion resistance, which can resist abrasion and chemical attack.

Product description:

Alumina tubes are made of alumina (Al2O3) ceramics. As a fine ceramic material, alumina is widely used in many industries. Alumina tubes have excellent electrical insulation, high chemical resistance and low thermal expansion, and these ceramic tubes are widely used in industrial ovens and machines. High purity alumina materials are ideal for the manufacture of alumina components for CVD, ion implantation, lithography and semiconductor manufacturing.

The main molding methods of alumina ceramic products are: dry pressing, isostatic pressing, injection molding and casting, different product shapes, sizes, complex modeling and precision products need different molding methods. Alumina ceramic products sintered at high temperature can only be processed using diamond grinding process.
Feature of alumina ceramic tubes：
1.High hardness
2.high wear resistance
3.corrosion resistance
4.high temperature resistance
5.corrosion resistance and bioinertness
Application of alumina ceramic tubes:
1. Parts for manufacturing CVD, ion implantation, lithography and semiconductor parts.
2. In traditional industries, alumina ceramics are the ideal choice for products such as spray tubes, gas nozzles and insulators.
3. It is used as a material in industrial furnaces because of its ability to maintain hardness at high temperatures.
4. Used as a high temperature thermocouple protector, 5. Due to its high corrosion resistance, used as a material in the chemical industry.

Advantages of alumina ceramic tubes:
Compared to metals and polymers, alumina tubes are preferred in extreme conditions. Its general characteristics and durability make it an important part of products that require durability but require low maintenance. This long-lasting quality makes it the first choice for producing long life products.
Other forms of piping made of various polymers or metals may need to be cleaned or replaced frequently. Once the alumina ceramic tubes are installed, they are guaranteed to last for many years. The chemical resistance and non-conductivity of alumina tubes make them perfect protectants and insulators.
