Jinzhou Yunxing Industrial Ceramics Co., Ltd. was established in 2000, mainly producing various types of tubular ceramic products and various industrial parts with alumina content above 99.3%. The factory covers an area of 4000 square meters.
The company currently has 3 1800 ° C high-temperature furnaces and 2 1400 ° C low-temperature kilns independently designed and manufactured. The molding process is mainly based on grouting molding, and has other molding process equipment such as extrusion and hot die casting.

Aluminium oxide is a highly stable compound and highly resistant to corrosion from salts, alkalines and acids. It can be used in the manufacture of thermocouple protection tubes, crucibles,boiler tubes and fire retardant material. 


Aluminium Oxide is a raw material used in the production of advanced ceramics. In the process of oxidization, oxygen molecules form a powerful bond with the aluminium, making aluminium oxide the hardest of all oxides.

Aluminium Oxide


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.
