The influence of polyvalent metal cations on the corrosion rate of molybdenum in molten glass

The corrosion behavior of molybdenum in a silicate melt has been studied using electrochemical techniques. The aim was to examine whether or not polyvalent metal ions such as iron (Fe3+), nickel (Ni2+) and cobalt (Co2+) are able to influence the corrosion behavior of molybdenum and, if so, to which extent. In addition the impact of the temperature of the melt on the corrosion rate has been addressed.
