POTASSIUM TUNGSTATE Chemical Properties,Usage,Production
Chemical Properties
Heavy, crystalline powder soluble in water, insoluble in alcohol.
Uses
Potassium tungsten oxide is used in solar energy and water treatment applications. It is used as alkaloids precipitating agent, bronze production and in tungsten refining. It is also used as an analytical reagent. Further, it is added to molten carbonate fuel cell to prevent the corrosion of stainless-steel separator and retards the sintering of the anode.
Purification Methods
Crystallise it from hot water (0.7mL/g).
