Silver Characteristic

  • Silver is similar in its physical and chemical properties to its two vertical neighbors in group 11 of the periodic table: copper, and gold.
  • Malleability: Silver is a relatively soft and an extremely ductile and very malleable metal, which means it can be easily shaped and formed into various objects. This property makes it ideal for making intricate and delicate patterns for both jewelry and decorative items.
  • Durability: Silver is highly resistant to corrosion and tarnishing, which makes it an ideal material for jewelry and other decorative items.
  • Conductivity: Silver is an excellent conductor of heat and electricity, which makes it useful in a wide range of industrial applications, including electronics, mirrors, and batteries.
    The thermal conductivity of silver is among the highest of all materials, although the thermal conductivity of carbon and superfluid helium are higher.
    The electrical conductivity of silver is the highest of all metals, greater even than copper. Silver also has the lowest contact resistance of any metal.
  • Color: Silver has a brilliant, white, metallic luster that can take a high polish, and which is so characteristic that the name of the metal itself has become a color name.
    Reflectivity: Protected silver has greater optical reflectivity than aluminum at all wavelengths longer than ~450 nm.
    Beauty: Silver is prized for its natural beauty, which is enhanced by its luster and shine.
    Antibacterial: Its antiseptic properties are based on the ability of the biologically active silver ion to irreversibly damage key enzyme systems in the cell membranes of pathogens.

 Gold Products & Utilization

Jewelry

Silver is commonly used in the creation of jewelry such as rings, bracelets, and necklaces.

Money / Finance

Due to its rarity, gold has long been used as a form of currency and people were using gold coins as far as 6000 years ago. about 10% of world gold is used in coinage or in financial stores of governments.

Investments

Silver is a popular investment asset, often purchased in the form of coins or bars (such as the American Eagle bullion coin from the US mint). Overall, silver’s rarity, durability, malleability, conductivity, and beauty make it a valuable and versatile precious metal.

Industrial Applications

Silver’s high conductivity makes it useful in many industrial applications, including electronics, solar panels, brazing alloys, dental products and batteries.

Medical uses

Antibacterial cream – silver sulfadiazine (SSD) is a topical antibiotic used in partial thickness and full thickness burns to prevent infection. Dressings – silver-containing dressings may increase the probability of healing for venous leg ulcers. Silver has antimicrobial effects, contributes to an improvement in quality of life and shows good cost-effectiveness. Endotracheal tubes.

Silverware

Silver is also used in the production of silverware, such as forks, spoons, knives, trays, cups, candlesticks, and religious articles.

Water purification

Electrolytically dissolved silver has been used as a water disinfecting agent, for example, in the drinking water supplies of the Russian Mir orbital station and the International Space Station. Many modern hospitals filter hot water through copper-silver filters to defeat MRSA and legionella infections.  The World Health Organization (WHO) includes silver in a colloidal state produced by electrolysis of silver electrodes in water, and colloidal silver in water filters as two of a number of water disinfection methods specified to provide safe drinking water in developing countries.
