Description of Light Mullite Stone
Aluminium Cordierite refractory bricks and Mullite Cordierite refractory bricks mainly consist of aluminium‐based raw materials combined with cordierite or mullite. This combination provides compressive strength, resistance to temperature fluctuations and a low coefficient of thermal expansion.
They contain low levels of iron and alkali metals, which contributes to their fire resistance. The higher aluminium content permits acceptable performance under reduced atmospheric conditions. Precise dimensions are maintained with thin, uniform bricks, resulting in masonry with measured strength and stability.
Application of Light Mullite Brick
Light Mullite Brick functions as a backing insulation layer for the fireproof lining of hot surfaces or other refractory materials. It is used in melting furnaces, firing kilns, chimneys, refinery installations, heating systems, regenerators, gas generators and pipes, soaking furnaces, annealing furnaces, reaction chambers and other similar industrial thermal installations.
