Application

Mainly used in aluminum smelting production to reduce melting point and improve electrolyte conductivity.Alcohol is used as an inhibitor in the production of by-fermentation.It is also used as a flux for ceramic and enamel glazes and as a component of glazes.It can also be used as a flux for smelting non-ferrous metals.
