Use of Industrial Waste in the Development of Ceramic Mass Compositions

The compositions of ceramic masses for facing slabs based on Angren secondary kaolin and clay were developed, using metallurgical waste–iron–containing dust from the gas cleaning of “Uzmetkombinat” JSC and sandy waste from the Toytepe fluorite enrichment plant. With the help of differential thermal and X–ray phase analysis, the chemical–mineralogical compositions, exothermic and endothermic effects of the used components of ceramic masses were determined during their heat treatment. Thus, the suitability of using these wastes for the development of the composition of ceramic masses has been established.
