General description

Sodium molybdate has corrosion resistant properties. On heating, it undergoes degradation and releases Na2O fumes.

Application

Sodium molybdate (Na2MO4) may be used as an electrolyte additive, for use in electrochemical capacitors. Addition of Na2MO4 as an electrolyte additive may result in enhanced capacitance, corrosion prevention and stabilized performance.
It may also be used as a catalyst during the manufacture of paints and dyes.
