Brown Fused Alumina(Brown aluminum oxide) is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion ,good corrosion-resistance and so on. After practical tests by dozens of refractory manufacturers, RS Brown Fused Alumina cant burst,pulverise and craze in the using course. In particular, its performance-cost ratio is much higher than traditional Brown Fused Alumina, making RS Brown Fused Alumina become the best aggregate and padding of brown fused alumina refractory materials.
