SEPPE Refractory Grade Calcined Bauxite

SEPPE calcined bauxite is produced by calcining of low iron, low alkali containing raw bauxites at temperatures of 1600 - 1800 degree Celsius. This removes moisture thereby increasing the alumina content.

Refractory grade bauxites have a high alumina content and a very low alkali content with low impurities (iron oxide and titania specifically), ensuring stable temperature strength. SEPPE refractory grade calcined bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore SEPPE calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
