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.
There are many models and specifications of alumina ceramic crucibles, which are not restricted by the production scale, batch size, and variety of smelting substances in application. They can be arbitrarily selected, have strong applicability, and can ensure the purity of the smelted substances.
The conventional capacity of alumina ceramic crucible is 0.1ml-6000ml. The output of alumina crucible is 5,000-10,000 per month; the production cycle is 5-30 days. The construction period of the special crucible is calculated based on the actual situation.

9.What is alumina crucible?
Aluminum Oxide Crucible, Al2O3
Alumina Crucible is made of raw material aluminum oxide. Alumina is a ceramic material with high thermal conductivity, compressive strength, high-temperature resistance, and thermal shock resistance.
10.What not to do with a crucible?
Hot crucibles should not be placed down on a cold surface. Ensure that manufacturers' recommendations for maintenance of furnaces are adhered to. Keep all inflammable material away from the furnace and ensure there is access to fire fighting equipment.
11.What is an alumina crucible made of?
99.3% Al2O3 Crucibles
Sintered alumina curcibles ideal for very high temperature applications up to 1700°C. It is resistant to chemical attacks from most acids and alkaline solutions as well as hydrogen and other reducing gases, with the exception of : High concentration hydrofluoric acid.
