| | POTASSIUM TUNGSTATE Usage And Synthesis |
| 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. | | reaction suitability | reagent type: catalyst
core: tungsten | | Purification Methods | Crystallise it from hot water (0.7mL/g). |
