<p>Platinum corrosion reducing amounts of a premelted oxide mixture that is PbO and B2O3, or PbO and SiO2, or PbO, SiO2 and B2O3 are added to raw batch ingredients for a lead-containing solder glass. All or part of the Pb3O4 or PbO normally used in the raw batch is replaced for advantages including reducing the amount of platinum corrosion in a platinum melter used to melt the raw batch to provide the glass.</p> |
