Silver oxide Silver oxide Silver(I) oxide is the chemical compound with the formula AgO. It is a fine black or dark brown powder that is used to prepare other silver compounds. Silver oxide can be prepared by combining aqueous solutions of silver nitrate and an alkali hydroxide. This reaction does not afford appreciable amounts of silver hydroxide due to the favorable energetics for the following reaction: US patent 20050050990 describes the preparation of AgO with properties suitable for use as a fine grained conductive paste filler. AgO features linear, two-coordinate Ag centers linked by tetrahedral oxides. It is isostructural with CuO. It
Silver prevent corrosion and tend to affect the lustre and colour of the alloy. Electrolytically refined pure silver plating is effective at increasing resistance to tarnishing. The usual solutions for restoring the lustre of tarnished silver are dipping baths that reduce the silver sulfide surface to metallic silver, and cleaning off the layer of tarnish with a paste; the latter approach also has the welcome side effect of polishing the silver concurrently. A simple chemical approach to removal of the sulfide tarnish is to bring silver items into contact with aluminium foil whilst immersed in water containing a conducting salt, such
