Odor: characteristic
Use: Potassium Sulfate is a moderately water and acid soluble Potassium source for uses compatible with sulfates.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy materials and fuel cells. Potassium Sulfate is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. We also produce Potassium Sulfate Solution. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards.
