Alumina Ceramic Tray is the main product of the factory; the output of conventional size alumina ceramic disc is 2,000-3,000 pcs / month; it is in stock.
Alumina Ceramic Tray
Alumina ceramic discs have been fired at a high temperature of 1800 degrees; they have good fire resistance; heat resistance; Alumina Ceramic Tray are widely used in chemical experiment projects. The raw material of alumina ceramic disc is alumina ceramic. It is a ceramic with a wide range of uses. Because of its superior performance, it has been increasingly used in modern society to meet the needs of daily use and special performance.
Application of alumina ceramic tray
Alumina ceramic tray is often used in chemical and physical grinding environment, especially high purity alumina is a very good material for producing wear-resistant components.
These components include shafts, pistons, bearings and mating end face seals. They are mainly used in chemical and physical conditions and are good corrosive media. These components can be used to manufacture circulating pumps, reciprocating pumps and resonator-supported products.
We use ceramic injection molding and grinding to produce a variety of complex components with strict surface finish and flatness requirements. At the same time, our manufacturing process can also meet the requirements of small and batch production.
Alumina ceramic tray is often used in water resources management, medical treatment, automobiles, telecommunications and household appliances applications.
We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramics 92% -99%.
2. The color of high purity alumina product is milky white, and other products are pink or white. The higher the purity, the more transparent the color.
3. Alumina is a refractory material, the higher the purity, the better the refractory effect
4. After high-purity alumina ceramics are fired and cooled in a 1800-degree high-temperature kiln, the products are not easy to break when they encounter high temperatures. Other ceramics are fired at 1500 ℃ ~ 1800 ℃.
5. The volume density of high-purity alumina> 3.92 g / cm3 has a smooth surface and is not easily corroded by chemicals. The bulk density of other ceramics is> 3.70 g / cm3 ~> 3.85 g / cm3.
6. High purity alumina has good hardness and good wear resistance.
7. High purity alumina products have a longer service life.
