| Zusammenfassung: | Заглавие с титульного экрана The composition of white porcelain enamel was developed, which has a set of specified properties, namely, high fluidity, high coefficient of thermal expansion, chemical resistance and whiteness. In contrast to the known enamels of the Na2O-B2O3-TiO2-SiO2 system, the resulting enamel has an expansion coefficient of 110•10-7 °С-1 (known compositions 80-95•10-7°С -1) and chemical resistance corresponding to class A+. The developed composition includes zinc oxide (4 wt %), a higher content of K2O (6 wt % K2O) compared to 105 the known compositions with a SiO2/B2O3 ratio of 3,6. This composition provides a fluidity of 53 mm, in contrast to the fluidity of 35-45 mm of known compositions. |
