Alumina Bubble Bricks for applications up to 1800°C/ 3270°F, these brick have excellent insulating properties and high hot strengths. Bubble alumina bricks are made with tiny hollow insulating spheres made from high-purity alumina (also called bubble alumina). Alumina does not exhibit high thermal conductivity, and when in the form of hollow spheres, its thermal conductivity is additionally reduced. Both properties made Bubble Alumina brick an excellent insulating material that can withstand exceptionally high temperatures. Typical applications for Bubble alumina bricks include gas or electrically heated kilns and furnaces as well as glass making industries.1. Low thermal conductivity. 2. High strength and resistance to corrosion. 3. Low heat capacity. 4. Low shrinkage after heavy firing. 5. High insulation. 6. High refractoriness. 7. Low density. 8. Good thermal shock resistance under high temperature. 9. Thermal insulation energy-saving effect is good.Alumina hollow ball brick used the alumina hollow ball, corundum powder, and calcined powders mixed at definite proportion as raw material. After mixing, drying, forming, firing at high temperature shuttle kiln made. Widely used in metallurgy, refractories, light industry, chemical industry, ceramic, glass, electronic industries. Can be used in cracking furnace, Hot Blast Stove, Shuttle kiln, heating furnace, tunnel kiln, push board kiln, pot furnace, and kinds of electric furnace and electrical kiln lining and so on.Widely used in metallurgy, refractories, light industry, chemical industry, ceramic, glass, electronic industries.
