Grinding chemically extracted alumina ceramic square rod/Stick
 



Alumina ceramic bar with high density, high refractoriness, good corrosion resistance, good mechanical capacity etc properties, and other characteristics, widely used in chemical fiber, textile, chemical etc industries.

All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680




 

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 ºC ~ 1800 ºC.
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.
