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 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℃.
