Complex fluxing agent based on natron, liquid glass and oxyethylidenediphosphonic acid for ceramics casting

The effect of a complex thinner based on soda, water glass and oxyethylidene diphosphonic acid on the rheological and casting properties of the Stephan Sсhmidt 13250 clay suspension and on the mechanical properties of dried and fired samples has been studied. The additive allows to reduce the moisture content of the clay suspension while maintaining its operating parameters. An increase in the strength and density of dry and fired clay specimens is observed, as well as a decrease in shrinkage and porosity.
