High-Purity Silver Sulfate from Aure Chemical – Your Trusted Source
Silver sulfate, Ag₂SO₄, CAS No. 10294-26-5, is a moderately soluble silver(I) compound valued for its controlled release of Ag⁺ ions and applications in analytical chemistry, materials science, and antimicrobial technologies. Supplied by Aure Chemical as fine white to slightly grayish crystalline powder with high silver content (approximately 69–70% Ag), this compound exhibits low solubility in water but dissolves readily in dilute acids, ammonia, and concentrated sulfuric acid. It serves as an efficient Ag(I) precursor for silver nanoparticle synthesis (via reduction), preparation of silver-based catalysts, antimicrobial surface treatments, and as a reagent in gravimetric analysis of sulfate or silver. Its sulfate anion provides a clean, non-halide source of silver ions, making it preferred in processes where chloride contamination must be avoided. Aure Chemical ensures precise Ag assay, low impurity levels, and secure silver sourcing to deliver batch consistency and optimal performance in laboratory, industrial, and high-tech applications worldwide.

Primary Applications of Silver Sulfate
Silver Sulfate provides a controlled-release source of Ag⁺ ions and is used in analytical, catalytic, and antimicrobial applications.
Gravimetric & Analytical Chemistry
Serves as a standard reagent for sulfate determination (precipitation of BaSO₄) and as a source of Ag⁺ in qualitative halide analysis and potentiometric titrations.
Silver Nanoparticle Synthesis
Used in reduction processes to generate Ag nanoparticles or colloids, particularly where sulfate counterions are preferred over nitrate or chloride.
Antimicrobial & Biocidal Applications
Incorporated into coatings, textiles, and medical devices for slow release of Ag⁺ ions with strong antimicrobial activity against bacteria and fungi.
Supported Silver Catalyst Preparation
Employed as a precursor for depositing Ag on supports via reduction or decomposition, useful in selective oxidation and ethylene oxide catalysis.
Advanced Materials & Electrochemistry
Used in preparation of silver oxide/sulfate composites, reference electrodes, and functional materials requiring controlled silver ion release.
Photography & Historical Processes
Employed in certain silver halide emulsion preparations and traditional photographic techniques where sulfate anions are compatible.
