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
Symbol Symbol A symbol is a mark, sign or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise very different concepts and experiences. All communication (and data processing) is achieved through the use of symbols. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river. Numerals are symbols
