Alumina Bubble

Alumina Bubble Product description: MainPhysicalandChemicalIndex:FunctionMullite ZS-75Chemical Composition%AL2O374-79 72-76MgO-SiO220-25 22-26Alumina Bubble is a kind of light heat protection refractory material. It is hollow sphere formed by blowing the melted alumina in the arc furnace. With the characteristic of light, obturator and heat resistance, it is the ideal filling material for the high temperature kiln, good aggregate for the high temperature light refractory castables and also the superior heat resistance, heat protection, energy conservation refractory materials. It can be used as heat protection castbles for high or over high temperature, light aggregate for high temperature fire resistance concrete, high temperature castables as well as high temperature energy conservation down-draft kiln, shuttle kiln, molybdenum wire furnace, tungsten bar furnace, induction furnace and nitriding furnace. It achieves noticeable result in the area of lighten the furnace weight, reform structure, save material and energy. Physical and Technical IndexAlumina Bubble
