PURPOSE:The titled enamel frit, consisting of SiO2, B2O3, Na2O, K2O, Li2O, CaO, BaO, Al2O3, ZrO2, F2, MoO3, MnO2 and Fe2O3, and having improved dipping characteristics, water resistance and adhesion under low-grade treating conditions. CONSTITUTION:An enamel frit, prepared by incorporating 32-45wt% SiO2 with 7-20wt% B2O3, 14-22wt% Na2O, 0.4-5wt% K2O, 0.3-2wt% Li2O, 1.5-15wt% CaO, 1.5-15wt% BaO, 0.5-5wt% Al2O3, 0.5-4.5wt% ZrO2, 2-9wt% F2, 0.4- 5wt% MoO3, 0.1-2wt% MnO2, 0.3-2wt% Fe2O3 and if necessary 0.1-5wt% ZnO and <=3wt% at least one component selected from MgO, SrO, TiO2, SnO2 and V2O5, and melting the resultant mixture under heating.
