Ceramic pigments based on raw materials of Uzbekistan

Compositions of green, blue and turquoise ceramic pigments have been obtained using the principles of heterovalent atomic substitution based on calcium aluminosilicate anorthite, replacing calcium and silicon ions with transition elements and aluminum using quartz sand from the Navoi deposit, Samarkand chalk and alumina-containing waste of the Shurtan gas chemical complex. The physicochemical properties of pigments have been studied. On the basis of the developed compositions of ceramic dyes, an experimental-industrial batch of decorative majolica was produced.
