The Many Uses of Gold

Posted on November 19, 2011 by admin There have been 0 comments

Did you know that gold was directly influential in laying the foundation of Chemistry? A long time ago, alchemists were obsessed with turning lead into gold (and silver) through the use of the mythical substance, philosopher's stone. They never succeeded in doing this, but it launched a different kind of interest--using and manipulating substances. And so, the birth of Chemistry arrived--all because of a fascinating obsession with a dense, ductile, and malleable metal called gold.

Gold has been an important part in the history of many countries, and it still is an important material in modern times.  However, its importance as a popular accessory or fashion jewelry has expanded into different areas; and it’s not even surprising how it has grown to become an important part of a society's development.

Here are the reasons why:

 Electronics

Gold is highly-resistant to corrosion and electrical conductivity. It is used as electrical wiring in many high-energy applications, such as the Manhattan Project's atomic experiments. It is also used in USB, video, and audio cables, and was also used to connect semiconductor devices through the wire bonding process.

Medicine

Gold is highly-beneficial in reducing pain and swelling of tuberculosis and rheumatoid arthritis. Gold salts are believed to have anti-inflammatory properties, although radioisotopes and salts are used, not the metallic gold we are all familiar with. It is also used in tooth restorations, and gold alloys are commonly used to restoring crowns and permanent bridges. Many dentists say that gold is better than porcelain crowns because it is slightly malleable, making the surface of the molars fit and adjust accordingly when they come into contact with each other.

Industry

Gold has a lot of industrial uses:

  • It can be used in embroidery as gold thread.
  • It is used as a protective coating on many artificial satellites.
  • Space vehicles are fitted with gold-coated polyester film to help stabilize the spacecraft's temperature.
  • High-end CDs ofen use gold as a reflective layer.
  • It acts as a lubricant between the mechanical parts inside a space vehicle. Gold has low shear strength, unlike organic lubricants that can be easily broken down easily by intense radiation outside of the earth's atmosphere.
  • Gold can be used to dissipate heat in automobile engines.
  • It is also placed on an astronaut's helmet. A thin film is placed on the visor to help reflect the solar radiation in space. This assures that the astronaut's skin and eyes are well-protected.

Food

Gold can be eaten, although it doesn't have any nutritive value or taste. Many gourmet chefs use gold leaf, dust, or flakes to decorate desserts and drinks, and even very expensive cocktails are decorated with gold leaf as well.

Investment

Gold was once used in financial transactions, with some even dating back to 6,000 years old. The U.S. and many other countries once used a "gold standard”, where they had a stockpile of gold to back up every dollar that was in circulation.

Today, they are now purchased as a valuable investment, with the Canadian Gold Maple Leaf, the American Buffalo gold bullion coin, and the Australian Gold Kangaroos having the highest gold purity (99.99%) of them all. Today, the most famous gold coins are the Chinese Gold Panda and the Austrian Vienna Philharmonic bullion coin.
