① Tabular alumina measurement is based upon Chinese standard test methods,YB/T 4216-2010

Tabular Alumina

This product has high volume density and good volume stability after high-temperature firing. It can be widely used in industries such as steel refractory, casting, ceramics, etc. Its application in the refractory industry for steel production almost covers the entire process of ironmaking and steelmaking. It can be used as the main component in aluminum carbon, aluminum magnesium carbon, magnesium aluminum carbon, magnesium spinel, and aluminum chromium refractory bricks, as well as introduced as enriched alumina into high alumina amorphous refractory materials.

Our tabular alumina products have the following characteristics:

-Low water absorption rate can significantly reduce the amount of water added to the casting material, as well as the amount of shaped refractory products and binders added;

-Low porosity and impurity content can improve the corrosion resistance of refractory materials under various atmospheres;
