Light weight high alumina brick, also known as high-aluminium heat insulating brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulating heat. Welcome to buy light weight high alumina bricks at RS Light Weight High Alumina Brick Supplier, we have high quality light weight high alumina brick at a low price! We can produce customized high quality products to meet your special needs!
Light Weight High Alumina Brick Chemical Composition & Properties
Light weight high alumina bricks contain more than 48% alumina oxide. This kind of brick does not directly exposed to high temperature inside kilns or furnaces, it only built closely to the kiln wall as insulations.
It is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.
It is a light weight refractory material mainly contains mullite, glass phase or corundum. See index chart:

Light Weight High Alumina Brick Applications & Uses
The brick is used in parts that is not exposed to abrasions and high temperature of melted matters. They should not be applied in environment that has a temperature higher than 1350℃.
As a low price refractory material, the light weight high alumina bricks are applied in:
※Furnace Lining And Insulation Layers
※Ceramic Tunnel Kiln
※Heating Furnace & Coking Furnace In Iron And Steel Industry
※Other Thermal Equipment & Heat Treatment Lining
Light Weight High Alumina Brick Producing Technique
Usually light weight high alumina bricks are made from high alumina bauxite and a small amount of clay, sometimes using industrial alumina to replace some bauxite clinker. After grinding into dust, we adopt gas evolution method or foam method to cast the material into form. At last the material would be sintered at 1300 to 1500℃.
