Studying the physicochemical regularities in the color- and phase formation processes of clinker ceramic materials

Abstract

The paper reports results of a comprehensive study, aimed at developing formulation-technological parameters for obtaining volumetrically dyed clinker ceramic materials with a wide range of colors. A possibility has been proven to obtain a ceramic clinker when using the polymineral clay raw materials at a temperature of 1,100 °C. The expediency has been shown to replace expensive ceramic pigments in the composition of masses with anthropogenic materials containing the oxides of metals with variable valency: wastes from alkaline earth syenite extraction, pegmatite enrichment, and production of ferrotitanium alloys. This shows possibilities for reducing the production cost of clinker ceramic articles. The influence of the formulation of raw materials compositions on the processes of color- and phase-formation of ceramic clinker has been investigated, depending on the character of furnace atmosphere.
