Experiences in the Production of Wall Ceramics with the Addition of Carbonate-containing Wastes

Abstract

The use of mining and metallurgical industry wastes containing calcium, magnesium, and strontium carbonates is described. The initial compositions and transformations occurring during the firing are considered. The best composition was chosen according to the results of laboratory studies, and based on that, ceramic brick was studied in real production conditions. The possibility of using mining and metallurgical industry wastes (dolomite and cake) as coloring pigments in the production of ceramic bricks has been theoretically substantiated and experimentally proven. Magnesium and strontium carbonates, along with calcium carbonates, participate in the formation of multicomponent systems, on the basis of which it is possible to obtain wall ceramics that meet modern requirements.
