ceramic· JVASP-57254· K2S2O7
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.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
