Bubble Alumia Bricks use Bubble Alumina, Tabular Alumina and White Fuse Alumina as raw materials. It has very high refractoriness and can work as working lining for some high temperature industrial furnaces. As the low thermal conductivity compared with corumdum bricks, it is an energy saving and green high end refractory materials.
