Glass Melting Moly Electrode>>
Molybdenum Electrode Physical Properties
Molybdenum electrode chemical properties is stable at normal temperature and pressure and it will not react with hydrochloric acid, hydrofluoric acid, nitric acid and alkali solution, but in the high temperature will occur oxidation. When the temperature is 400 ℃, there is slight oxidation and when the temperature is 600 ℃, there is intense oxidized.
