Refractory white fused alumina for cement and castable
White corundum/white fused alumina is a high-quality refractory material, which is made by melting and cooling high-quality alumina in an electric arc furnace above 2000°C.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity, mainly used for refractory industrial.
0-1mm Refractory white fused alumina
1,High hardness and dense particles. Single particle roundness is good.
2, The color is pure white, no impurities, to ensure the wear-resistant layer or wear-resistant paper color and transparency.
3, Uniform distribution of particle size, single particle shape consistent, with a small amount of wear – resistant effect.
4, Chemical stability and acid, alkali no action, high temperature stability is very good.

Henan sicheng Abrasives Tech Co.,ltd was established in 2009. It covers the area of 10 years. With updated new equipment, our factory can produce White Fused Alumina 15,000 tons per year, Brown Fused Alumina 15,000 tons per year and Slilicon carbide 2,000 tons per year. It is one of the high grade refractory production base in China.
We have our own individual laboratory, the testing method for particle size is laser measuring method. From raw material choosing and purchasing, production processes, to market & sales, we all have very high standards. Which makes our products very popular among Japan, Korea, Southeast Asia, Middle East and European countries.
