Andalusite

     Concentrate properties and uses of andalusite: andalusite are quality aluminum V soil. Resistance Kaolin
Fire materials. It has high refractoriness, thermal shock resistance to chemical corrosion, and a good
Electric insulation properties, thermal-mechanical strength, thermal creep small volume, high temperature thermal load
Lan and conservation of energy, and many other advantages. Hot Stove widely used brick, ladle lining brick,
Cypriot first burned brick, brick and small mouth with high load softening point, the stability of the Gaolu:zhuan high fever,
Hot Stove high alumina ceramic burner and burning castable refractory brick, and other special and non-stereotyped
Refractory area.
