Refractory brick is a kind of insulation material adoption organic matter as ignition loss substance
in order to increase the porosity, small volume density , good insulation effect, high mechanical
intensity , small thermal conductivity and low heat storage. They are widely used in Fire – Clay
Insulating Refractory Brick, High-Alumina Insulating Refractory Brick , Diatomaceous Insulating
Brick, High Grade Insulation Brick :XJM Series Light-Weight Insulation Brick , B Series Thermal
Insulation Brick, Calcium Silicate Insulating and Refractory Products, Clay Insulation Brick, Foam
Diatomite Insulation Brick, and Light –Weight Insulation Brick.
Lower heat storage than denser refractories
low levels of iron and other impurities
Lightweight and energy-efficient
High compressive strength
Typical application of High temperature high density white color bricks Polycrystalline mullite bricks
Electrolytic Aluminum Industries
Iron & Steel Industries
Non-Ferrous Metals Industries
Glass Industries
Ceramics Industries
