Light Mullite Brick Description
Aluminum cordierite refractory bricks and mullite cordierite refractory bricks are mainly composed of aluminum raw materials combined with cordierite or mullite to ensure high compressive strength, thermal shock resistance, and low thermal expansion coefficient.
It has a very low iron and alkali metal low melt content and therefore it has high refractoriness. The higher aluminum content allows it to maintain good performance under a reduced atmosphere. Precise dimensions: masonry, thin and uniform bricks. The masonry has high strength and high stability.
Light Mullite Brick Application
Light Mullite Brick can be used as a backing insulation layer for hot surface refractory lining or other refractory materials. It can be used in melting furnaces, firing kilns, flues, refining equipment, heating equipment, regenerators, gas generators, and pipes, soaking furnaces, annealing furnaces, reaction chambers, and other similar industrial thermal equipment.

Light Mullite Brick FAQs
How are Light Mullite Bricks used in furnace construction?
Light Mullite Bricks are typically used as the insulating layer, combined with dense refractory bricks for better energy efficiency.
Are Light Mullite Bricks resistant to slag and chemical corrosion?
They have good resistance to chemical corrosion from acidic and neutral slags but are less resistant to alkaline environments.
What type of mortar is used for Light Mullite Bricks?
High-temperature insulating mortar or lightweight refractory cement is typically used for bonding.
