Abstract

Ta, Nb, Ti, and Zr corrosion for six different molten glasses have been experimentally studied at 1400°C. Both corrosion-layer compositions and corrosion rates have been determined. Mechanisms of corrosion-layer formation, mainly based upon both redox reactions between metal and glass and solid-state diffusion, are proposed. The consequences of metallic element additions to the glass on metal corrosion are discussed in comparison with a metal-free reference glass. The corrosion rates of niobium are specifically determined in a Na₂O3.5SiO₂ glass modified by additions of metallic elements. A correlation is established between the corrosion rate and the formal redox potential of the M^II/M⁰ couple.
