Description

The metal silver is described as a white, lustrous solid. In its pure form it has the highest thermal and electrical conductivity and lowest contact resistance of all metals. With the exception of gold, silver is the most malleable metal.

Silver (symbol Ag) is one of the basic elements present in the earth's crust. Silver is rare, but occurs naturally in the environment as a soft, “silver”-colored metal or as a white powdery compound (silver nitrate). Metallic silver and silver all

Silver Use and Manufacturing

Methods of Manufacturing

Industrial production uses electrolysis, that is, using metallic silver as a raw material, dissolved in nitric acid, and formulated into an electrolyte composition: containing Ag50 g/L, HNO33～10 g/L, and adding an electrolytic cell for electrolysis. The electrolyte temperature is about 45°C, the cell voltage is 2.5 V, and the cathode current density is 2.5 to 2.7 A/cm2. After electrolytic refining, a high-purity silver powder product is prepared.

Uses

For coinage, most frequently alloyed with copper or gold; for manufacture of tableware, mirrors, jewelry, ornaments; for electroplating; for making vessels and apparatus used in manufacture of medicinal chemicals, in processing foods and beverages, in handling organic acids; as catalyst in hydrogenation and oxidation processes; as ingredient of dental alloys.Has been used for purification of drinking water because of toxicity to bacteria and lower forms of life.Some salts used in photography.
