We only make high purity alumina ceramics
1. High-purity alumina content 99.3% -99.5%, other alumina ceramic92% -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.

FAQ
A1. Alumina (Al2O3) is a widely used material for highly insulating films due to its very low electrical conductivity, even at high temperatures.
A2. In more cutting-edge industries, alumina tubes are widely used as components in hi-tech process equipment. Applications include: Parts for CVD, ion implants, photolithography, and semiconductor systems. A high voltage insulator in plasma cleaning systems for aluminum rolling and coating mills.
A3. Not combustible. In case of fire in the surroundings, use appropriate extinguishing media.
A4. Of all the metal oxides, alumina performs best in this role as an amphoteric ion exchanger. In comparison the more commonly used silica only allows for a cation exchange due to its low pH pzc. Alumina is stable. It overcomes the relatively low and high pH instability of silica.
