Zinc-containing, lead- and cadmium-free glass frits, method of their production and their use

摘要

Zinc-containing, lead- and cadmium-free glass frits with a softening point of less than 510 DEG C. are disclosed. Obligatory components of the glass-frit composition are 31-50 mole % ZnO, 10-44 mole % SiO2, 11-35 mole % B2O3 and 11-25 mole % Na2O. The glass frits can be used as base frit for the production of decorative coating masses which can be stoved below 630 DEG C., preferably masses for the decorating of glass.
