Combined effect of alumina, phosphorus, and sodium oxides on the structure and properties of boron-free titanium enamels

The effect of complex additives Na ₂ O, Al ₂ O ₃ and P ₂ O _{5 on the structure and physicochemical properties of boron-free titanium enamels. It has been established that the introduction of Na 2 O into boronless titanium enamel together with Al 2 O 3 or P 2 O < sub> 5} (in optimal ratios 1: 1 and from 1: 1 to 2: 1, respectively) instead of a part of SiO ₂ contributes to the expansion of the "cationic assortment" of network formers in glasses and an increase in their fusibility without reducing the whiteness of enamel coatings obtained on their basis.
