Vice White Fused Alumina,also named Grey Fused Alumina,Brown Corundum or Sub White Fused Alumina, is a electro fused corundum with color similar to Brown Fused Alumina but lighter, and chemical and physical specifications to White Fused Alumina(WA). It has a Aluminium Oxide(Al2O3) content of *7%min for most sizes which is close to WA.

It’s invented by a Japanese company to replace White Fused Alumina for refractories at the time when WA was much more expensive than BFA. At this time, it is not very popular,but still some customers like it,mostly because of its higher content of Al2O3 and higher true gravity density than Brown Fused Alumina

.It is also produced out of high quality bauxite in electric arc furnaces in high temperature and has similar manufacturing to BFA.
Mostly used as a refractory mineral, Vice White Fused Alumina can be used for high quality refractory bricks, refractory mortars, refractory castable, refractory crucibles, gunning materials, lining materials,pre-casting materials etc. It has very good heat resistant and thermal stability characters.

Vice White Fused Alumina Characters
1.Refractory/Fireproof
Vice White Fused Alumina has Aluminium Oxide(Al2O3) content of more than *7%,which is higher than BFA. It features high temperature resistance, thermal stability, corrosion proof and low porosity. These features are important to fireproof and refractory products.
2.Low Impurities
Vice White Fused Alumina has about only 0.8%max SiO2 and lower Fe2O3 than Brown Fused Alumina. SiO2 and Fe2O3 are easy to cause corrosion, rust stain, cracks, dark spot etc when making refractory bricks. High impurities will be better for it.
3.High Density
Vice White Fused Alumina is density material with higher true gravity/density. This makes it a better material for making refractory products with higher density and durable performance.
