Alumina Ceramic



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.
