History

(Anglo-Saxon, Seolfor siolfur; L. argentum) Silver has been known since ancient times. It is mentioned in Genesis. Slag dumps in Asia Minor and on islands in the Aegean Sea indicate that man learned to separate silver from lead as earl as 3000 B.C.

Sources

Silver occurs native and in ores such as argentite (Ag2S) and horn silver (AgCl); lead, lead-zinc, copper,
gold, and copper-nickel ores are principal sources. Mexico, Canada, Peru, and the U.S. are the principal
silver producers in the western hemisphere.
Production
Silver is also recovered during electrolytic refining of copper. Commercial fine silver contains at least
99.9% silver. Purities of 99.999+% are available commercially.
Properties
Pure silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and
malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and
thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and
water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. The alloys of silver
are important.
Uses
Sterling silver is used for jewelry, silverware, etc. where appearance is paramount. This alloy contains
92.5% silver, the remainder being copper or some other metal. Silver is of the utmost importance in
photography, about 30% of the U.S. industrial consumption going into this application. It is used for
dental alloys. Silver is used in making solder and brazing alloys, electrical contacts, and high capacity
silver-zinc and silver-cadmium batteries. Silver paints are used for making printed circuits. It is used in
mirror production and may be deposited on glass or metals by chemical deposition, electrode position, or
by evaporation. When freshly deposited, it is the best reflector of visible light known, but is rapidly
tarnished and loses much of its reflectance. It is a poor reflector of ultraviolet. Silver fulminate, a
powerful explosive, is sometimes formed during the silvering process. Silver iodide is used in seeding
clouds to produce rain. Silver chloride has interesting optical properties as it can be made transparent; it
also is a cement for glass. Silver nitrate, or lunar caustic, the most important silver compound, is used
extensively in photography. Silver for centuries has been used traditionally for coinage by many countries
of the world. In recent times, however, consumption of silver has greatly exceeded the output.
