Galvanic corrosion of glass tank refractories

GT V2 1961 053-059

Galvanic measurements are used to follow chemical reactions between representative glass tank refractories
and molten glass. The corrosion patterns of the refractories correlate with the characteristics of the refractory glass cells. The ability of the electrolytic cells to generate a current was measured and used as an indication of the rate of the corrosion reaction. The effect of applying an external potential to the refractory is reported.
