Vice-white fused alumina/BFA98%/Brown fused alumina 98%/ Sub-white fused alumina/Gray fused alumina
Vice-white Fused Alumina is made by a special technique in electric arc furnaces with high temperature above 2300C; 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 pulverising in the process of Brown fused alumina 98% replacing aluminum-oxygen based corundums such as white fused alumina. RS Brown fused alumina 98% is the ideal product which can substitute white fused alumina, compact fused alumina and tabular alumina in China .
RS Brown fused alumina 98% sand (Barmac plastic) and micropowder (acid washing) 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.
