Use of wastes from concentration of alkali syenites from the elet’ozerskoe deposit for manufacture of ceramic tiles
Source abstract
Abstract
The effect of the mineralogical composition of wastes from concentration of alkali syenites on the structure and properties of ceramic tile was established. The ceramics obtained after firing at 950 – 1100°C have an irregularly granular structure consisting of a fine-grained base (grain size less than 5 μm) and disseminated deposits 10 – 50 μm (in ceramics with slurry) and up to 120 μm (in ceramics with a magnetic fraction) in size. The glass phase is enriched with aluminum, magnesium, and iron oxides contained in syenite concentration wastes and has an inhomogeneous chemical composition. It was shown that the higher content of iron minerals in the magnetic fraction in comparison to slurry significantly intensifies glass formation and sintering of the ceramic, causing low water absorption and high strength.
