Claim 5:
6. A preparation method for an enamel composition, comprising:
supplying materials for the enamel composition, the enamel composition including 20 wt % to 60 wt % of phosphorus pentoxide (P2O5), 1 wt % to 20 wt % of silicon dioxide (SiO2), 1 wt % to 30 wt % of boron trioxide (B2O3), and 10 wt % to 30 wt % of at least one of lithium oxide (Li2O), sodium oxide (Na2O), and potassium oxide (K2O), and 10 wt % to 40 wt % of at least one from a group consisting of post-transition metal oxides and transition metal oxides such that the enamel composition includes 5 wt % to 20 wt % of zinc oxide (ZnO) and 1 wt % to 20 wt % of molybdenum trioxide (MoO3);
melting the materials for the enamel composition; and
cooling the melted materials in a quenching roller and forming the enamel composition.
