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 carbonate Silver carbonate Silver carbonate is the chemical compound with the formula AgCO. Silver carbonate is yellow but typical samples are grayish due to the presence of elemental silver. It is poorly soluble in water, like most transition metal carbonates. Silver carbonate can be prepared by combining aqueous solutions of sodium carbonate with a deficiency of silver nitrate. Freshly prepared silver carbonate is colourless, but the solid quickly turns yellow. Silver carbonate reacts with ammonia to give the explosive fulminating silver. With hydrofluoric acid, it gives silver fluoride. The thermal conversion of silver carbonate to silver metal proceeds via formation of
