Potassium disulfate (K₂S₂O₇) is an inorganic ceramic compound belonging to the sulfate family, commonly encountered as a byproduct in industrial sulfuric acid production and as a laboratory reagent. It serves primarily in metallurgical applications—particularly in metal pickling, surface treatment, and ore processing—where its strong oxidizing and acidic properties facilitate corrosion and scale removal from steel and other metals. This material is notable for its thermal stability at moderate temperatures and its compatibility with aqueous processing streams, making it a cost-effective alternative to other mineral acids and oxidants in heavy industrial settings.
