Calcined bauxite manufacturers in China
Calcined bauxite manufacturers in China Calcined bauxite is produced by sintering/calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 – 1800 degree 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.
