Pharmaceuticals

Silver is leading a revolution in technology and medicine. The white metal's unique bacteria-fighting qualities are becoming more and more critical in healing conditions ranging from severe burns to Legionnaires Disease. In fact, the most powerful treatment for burns is silver sulfadiazine, which is used in every hospital in North America to promote healing and reduce infection. Everything from surgical threads to bandages and dressings to doctors' coats and catheters are utilizing silver. In hospitals and homes, silver in ductwork provides maximum sterile atmosphere.

Electrical

Silver is the best electrical conductor of all metals. Because it does not corrode, its use in electrical and motor control switches is universal. A fully-equipped automobile may have over 40 silver-tipped switches to start the engine, activate power steering, brakes, windows, mirrors, locks and other electrical accessories

Chemical Catalyst

Silver is also one of the few elements that improve the efficiency of chemical reactions. It is the only catalyst that will oxidize ethylene gas into ethylene oxide, the building block for polyester textiles used for clothing and specialty fabrics, and melded items like computer keyboards, electrical control knobs, domestic appliance components and Mylar tape used for all audio, VCR and recording tapes. Nanotechnology applications using silver are growing -- in computers, communications, miniature motors and switches.

Reflectants

Silvered windshields in homes, cars and office buildings reflect away some 70% of the solar energy that would otherwise pass through, thus reducing the load on air conditioners. The U.S. Department of Energy's Energy Star Program has spurred 50% increase in silver-coated glass in past six years, translating to 350 million square feet of glass, or five million ounces of silver per year.

Industrial

Silver is the ideal industrial material. No other metal has silver's combined strength, malleability and ductility, or facilitates electrical and thermal conductivity as well, or can reflect light and endure such extreme temperature changes. Jet engines of today and tomorrow can depend on silver-coated bearings for their performance and safety. All major jet engine manufacturers utilize these high-performance silver bearings, which provide critical fail-safe lubrication required by the Federal Aviation Administration.

Printed Circuitry

Printed circuit boards (PCBs) use silver for connecting paths of electronic circuitry. PCBs are essential to the electronics that control the operation of aircraft, automobile engines, electrical appliances, security systems, telecommunication networks, mobile telephones, television receivers. Most computer keyboards use silver membrane switches.

Superconductors

These low-current switches are also found in control panels of cable television, telephones, and devices using digital electronics. Superconductivity is the power transmission of the future and silver makes it faster and more effective. Silver-jacketed superconducting oxide wires can carry more than 140 times the electric load of copper wire with less than 1 percent of the weight. This wire utilizes about 1,000 ounces of silver per mile. Silver already improves performance at lighter weights and size in cables, motors, generators and transformers. Silver oxide-zinc batteries provide higher voltages and longer life for such consumer goods as quartz watches, cameras, and electronic tools.

Electroplating

The ease of electrodeposition of silver accounts for silver's widespread use in coating. The plating thickness of some items, such as fuse caps, is less than one micron although the silver then tarnishes more easily. Coatings of two to seven microns are normal for heavy duty electrical equipment. Silver plating is used in a wide variety of applications from Christmas Tree ornaments to cutlery and hollowware.

Brazing & Soldering

Silver facilitates the joining of materials (called brazing when done at temperatures above 600oCelsius and soldering when below) and produces naturally smooth, leak-tight and corrosion-resistant joints. Silver brazing alloys are used widely in applications ranging from air-conditioning and refrigeration equipment to power distribution equipment in the electrical engineering sector. It is also used in the automobile and aerospace industries.

Coins

Silver, being a rare and noble metal, was a more desirable medium of exchange than beads, feathers, shells, and the like. Its use as a medium of exchange is known throughout all recorded history. Coins, in the sense of having an authenticating stamp on them, began to appear in the eastern Mediterranean during 550 B.C. By 269 B.C. Rome adopted silver as part of its standard coinage. Silver became the trading medium for merchants throughout the civilized world. (Gold being reserved for governments and the wealthy.) Today silver coins continue to be the medium of exchange wherever paper is not acceptable, for example, in parts of Africa and the Middle East. One example of a trade coin is the Empress Maria Theresia Taler, first minted in Austria in 1741. It was standardized in 1780 as 28 grams and 833/1000 silver (the remainder copper). Some 370 million of these 1780 dated coins have been minted up to 1996 and a large proportion remain in circulation today.

Photography

Although a wide variety of other technology is available, silver-based photography will retain its pre-eminence due to its superior definition and low cost. From it's very outset, silver halide has been the material that records what is to be seen in the photograph. As little as 4 photons of light activate silver halides which amplify that incident light by a factor of one billion times. In today's photography, silver halides are coupled with dyes that bring the color of the world around us into permanent record. An estimated 196 million troy ounces of silver were used worldwide in 2003 for photographic purpose.
