Silver has many uses. The precious metal is a powerful antibacterial agent. Silver has the highest electrical conductivity among metals, which makes it an important industrial material. It is easy to process and is widely used in the production of electronic products and in the jewellery industry. The largest silver producers in the world are Mexico, Peru and China. In the last few years, these three countries have mined about 49% of this metal.

DID YOU KNOW THAT…

  • As an electrical conductor, silver is built into any car, TV, dishwasher, refrigerator, mobile phone (at least 250 milligrams), laptop (about 1 gram), etc.
  • Silver is widely used in the manufacture of batteries. Smaller electronic devices, such as hearing aids and electronic watches, run on silver-zinc, silver-cadmium or silver oxide batteries due to their long life.
  • Chemical reactions can be significantly accelerated by the addition of silver.
  • Approximately 700 tons of silver are used continuously in the global chemical industry for the production of plastics.
  • Silver is also used in pharmaceuticals. Silver sulfadiazine is the strongest ingredient in the treatment of burns.
  • Silver ions and silver compounds destroy pathogenic bacteria, viruses, algae and fungi. The antimicrobial action of silver continues to be the subject of research.
  • Only “silver water” is used on the International Space Station.
  • The largest piece of native silver on Earth weighs 1,420 kg and was discovered in Chile.
  • The term sterling is related to the composition of the English currency – sterling silver is an alloy containing 92.5% silver and 7.5% other metals, usually copper. The sterling silver standard has a minimum purity sample of 925.
  • Silver plays a leading role among metals in the jewellery industry. In its purest form – 99.9%, silver is extremely soft for making jewellery. To gain strength, it is usually mixed with copper (Cu).
  • A European standard has been adopted in the production of silver jewellery – silver has a purity of 92.5% (sample 925), which means that out of 1000 units, 925 are pure silver and the remaining 75 are copper.
  • Each year, patents issued for the application of silver as a metal outnumber those for the applications of all other metals combined.
  • While common silver markets are dominated mainly by established “conventional” uses, there are a number of new technologies that also use silver, and these rapidly evolving technologies will explain the disproportionately high growth of the silver market.
  • Silver is particularly suitable for inks, in part because of the properties of its oxide and because the contact resistance between the particles deposited by the ink is extremely low.
