Molybdenum electrode improves solar glass

It is suitable for glass production in the solar industry. For this duty, the glass is refined in the melting tank using antimony oxide which can cause molybdenum electrodes to break rapidly. MoZrO2 can withstand these attacks much longer, preventing or significantly delaying breakage and electrode loss, the company says.

Doping molybdenum with small amounts of ZrO2 also improves corrosion resistance against molten glass, and increases high-temperature strength. When used in the manufacture of the SO4 refined glasses used in the container industry, the doped MoZrO2 glass-melting electrode reportedly shows much better corrosion resistance in white, brown and green glass. Laboratory tests showed that it can decrease the corrosion rate on molybdenum glass melting electrodes up to 40%.

The electrode was launched at the DGG & ESG conference in Magdeburg, Germany at the beginning of June.
