THE MECHANISM OF DISSOLUTION OF MOLYBDENUM IN GLASS MELT AND THE EFFECT OF ALTERNATING CURRENT

J. Matěj, E. Krupková, V. Hulínský

The molybdenum corrosion and lead precipitation rates together with the overall electrode current were investigated in terms of the potential of the molybdenum electrode in three glass melts. Two of them contained 24 wt.% lead oxide, one of them containing also a small addition of arsenic oxide, and the third glass melt was free from lead oxide. The comparison of the rate of precipitating lead, of the corrosion rate and of the total electrode current in the melt free from arsenic oxide showed that molybdenum is for the mos
