RS Vice-White Fused Alumina
1.Description
With high-purity alumina bauxite as main raw material , RS Vice-white Fused Alumina is made by a special technique in electric arc furnaces with high temperature above 2300 degree and refining with longer time.
It is characterized by high temperature resistance, corrosion and erosion resistance, low apparent porosity and stable thermal stability performance.

It solves such problems as bursting, crazing and pulverizing in the process of Vice-white fused alumina replacing, compact fused alumina and tabular alumina in China.

RS Vice-white fused alumina sand (Barmac plastic) and micropowder (acid washing) produced by Rui Shi plant is characterized by without bursting, without pulverising and high bulk density, good flow property etc, which can be widely used to manufacture variety of shaped refractory material products, corundum castable refractory, and other monholithic bulk refractory and caustic-burned corundum refractory products.
