The Effect of Variable Ratios of Na₂O/K₂O Oxides in Glazes Containing BaO, ZnO, and ZrO₂: Structural Analysis, Characteristic Temperatures, and Surface Properties

Applied Sciences
In this paper, the glazes of a multicomponent system (SiO2-Al2O3-CaO-MgO-Na2O-K2O-BaO-ZnO-ZrO2) were examined. This work focuses on five glazes and the difference between them as the molar ratio of the alkali oxides Na2O/K2O.
