Potassium Pyrosulphate

Product Description

Potassium Pyrosulphate (K₂S₂O₇) is a white crystalline inorganic compound primarily used as a flux and dehydrating agent in analytical chemistry. It decomposes upon heating to form potassium sulphate and sulphur trioxide, making it highly valuable for sample decomposition and fusion processes.
Due to its strong acidic and oxidizing nature, Potassium Pyrosulphate is commonly employed in laboratories for preparing samples for analysis of refractory materials, metals, and oxides. It is also used in industrial processes requiring controlled oxidation or high-temperature chemical transformations.
