Andalusite Refractory Brick Description
Andalusite Refractory Brick is a type of refractory material that is made from andalusite, a mineral that is composed of aluminum silicate. Andalusite refractory bricks have excellent high-temperature properties, such as high refractoriness, good thermal shock resistance, and low thermal expansion. These bricks are commonly used in high-temperature industrial applications, such as in the lining of kilns, furnaces, and reactors, where they provide insulation and protection against extreme heat and chemical corrosion.
