High-Purity Silver(I) Oxide from Aure Chemical – Your Trusted Source
Silver(I) oxide, Ag₂O, CAS No. 20667-12-3, is a versatile and widely used silver(I) oxide known for its strong oxidizing properties and applications in catalysis, materials, and antimicrobial technologies. Supplied by Aure Chemical as fine dark brown to black powder with high silver content (approximately 93–94% Ag), this compound readily decomposes to metallic silver and oxygen upon heating and serves as a clean, halide-free source of Ag(I) or Ag(0) species. It is employed as a precursor for supported silver catalysts, silver nanoparticle generation, preparation of silver oxide thin films, and in alkaline battery cathodes (e.g., silver-zinc batteries). Its ability to activate oxygen and provide antimicrobial silver ions makes it valuable in selective oxidation catalysis, CO oxidation, and antimicrobial coatings/surfaces. Aure Chemical provides controlled particle size, high surface area options, and secure silver sourcing to ensure batch reproducibility and optimal performance in catalytic, energy storage, and materials applications worldwide.
