Introduction
Glass melting zirconia molybdenum electrodes (MoZrO2 molybdenum electrodes) are an electrode doped with a small quantity zirconia. Compared to pure molybdenum electrodes, zirconia molybdenum electrode not only retains the high temperature performance and thermal conductivity properties, and has greatly advanced in terms of corrosion resistance. Besides, during melting glass it exhibits excellent corrosion resistance and excellent high temperature strength. This new molybdenum electrode have been increasingly used in a variety of glass manufacturing.
