Název v původním jazyce

Cathodic behavior of molybdenum electrode in various glass melts

Popis výsledku v původním jazyce

The cathodic behavior of molybdenum electrode has been investigated in model glass melt of the basic composition of 16Na2O, 10CaO, 74SiO2 (wt.%) with additions of SO3 or Sb2O3 or without additions at 1400°C. There exists a range of catho-dic potentials reduced by some hundreds millivolts against the rest state where the reduction of electroactive species acting as depolarizers of molybdenum corrosion may be suppressed. The potentials of the maximum suppression of lead or antimony precipitation correspond to potentials at which the anodic molybdenum oxidation finishes. The layers of molybdenum silicides have been not found on the electrode at those potentials. In glass melt containing sulfur trioxide, the sulfur depletion of glass in electrode vicinitytakes place. At more reduced potentials, the subsequent formation of silicon and formation of the silicides Mo3Si, Mo5Si3 and MoSi2 occurs. The formation of silicon and silicides is impeded by presence of the electroactive glass component
