A Comparison between Andalusite and Bauxite as Refractory

Andalusite-based refractories possess superior refractory properties than bauxite based-refractories and can thus be used in applications where bauxite-based refractories are currently used. Andalusite-based refractories exhibit better thermo-mechanical properties like hot strength, HMOR, refractoriness under load (RUL), creep resistance, and thermal shock resistance.
