Alumina Bubble Bricks

High refractoriness.

► Good mechanical strength.
► Low thermal conductivity
► Good corrosion resistance.
► Good volume stability.

Description

Alumina bubble bricks are premium insulating bricks made from alumina bubbles. Alumina raw materials are melted in electric furnace and then blew into bubbles. The sizes of alumina bubbles can be adjusted according to requirement. The sizes of alumina bubbles greatly affects the performance of alumina bubble bricks, so it should be strictly controlled during production.   Alumina bubble bricks have very good high temperature performance and are widely used as the insulating of high temperature equipment, or as the working lining which don’t contact with molten materials.

Technical Data

Application

Alumina Bubble Bricks Applications

Alumina bubble bricks have the advantages of high refractoriness, high mechanical strength and low thermal conductivity. So alumina bubble bricks can not only be used at insulating lining of thermal equipment, but also be used at working lining of some high temperature kilns and furnaces. The main applications of alumina bubble bricks are Molybdenum silicide electric furnace, molybdenum wire furnace, tungsten furnace, high temperature gas intermittent kiln, tunnel kiln and so on. With the application of alumina bubble bricks, energy consumption is significantly reduced.   

RS company supplies different grades of alumina bubble bricks, including Sialon bonded alumina bubble bricks, pure alumina bubble insulating bricks, mullite bonded alumina bubble bricks, sialon bonded alumina bubble bricks, high alumina bubble bricks and so on. To make mullite bonded alumina bubble bricks, SiO2 powders should be into raw material, so mullite phase will be formed during sintering, which will improve shock resistance of alumina bubble bricks.
