Silver Powder

Silver is a chemical element with the symbol Ag (from the Latin Argentum, derived from H Iner In proto-Indo-European: “brilliant” or “white”) and atomic number 47. A smooth, white and glossy transition metal presents the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the earth’s crust in the pure and free elementary form (“native silver”), as an alloy with gold and other metals, and in minerals such as argentite and chlorite. Most silver is produced as a by-product of copper, gold, lead and zinc refining.

Silver has long been considered a precious metal. Silver metal is used in many coins, sometimes alongside gold: although it is more abundant than gold, it is much less abundant than native metal.  Its purity is typically measured per thousandth; an alloy of 94% purity is described as “0.940 fine”. As one of the seven metals of antiquity, silver has played a lasting role in most human cultures.
