Refractory Bauxite | Calcined Bauxite
Refractory Bauxite is produced by sintering and calcining low iron, low alkali containing raw bauxites at temperatures of 1600 - 1800 degrees Celsius. In this calcination process, the high refractory mineral phases corundum and mullite are formed. Refractory grade bauxite has high refractoriness, good mechanical strength, and moderate slag resistance. Therefore calcined …
