Facts About Gold

By Paul James Harrison

Some of the first discoveries of metallurgy relate to the properties of gold, which have become known to rich people and commoners alike. What is it that made gold so special in human history that pharaohs hoarded it in immense treasures and that even modern times have not tarnished its image, but added to its usefulness and beauty? Here are some facts based on which some answers may be found to this question.

For one, gold is indestructible, a fact which cannot be said about many other metals. By indestructible I am not referring to the toughness that iron or steel have. Actually, in this respect gold is very malleable and can be hammered in sheets so thin that leave the light pass right through. But I do refer to the fact that it is chemically immune, that it does not oxidize in contact with water and air and that cannot be attacked by even the strongest acids. The few chemical interactions that gold is part of are mostly combinations with other metals – such as silver, copper, zinc, nickel, platinum or iron – to produce alloys and the fact that it dissolves in mercury.

Electronics is one of the modern industries which discovered the benefits of gold – its electrical conductive properties to be more precise. The precious metal has one of the highest electric conductivity values, which make it ideal for the electronic industry, where its resistance to heat variations and corrosion also proved very valuable. Electronic producers employ gold to build printed circuit boards and electrical components used in top-of-the-line products, from computers to DVD players, TV sets and other electronic devices.

Medicine is one of the sciences which discovered early the properties of gold, which is still used in dentistry to produce false teeth. This use tends to fade out, as other more life-like materials are employed today. Gold is used in medicine for producing medical instruments and surgical lasers which allow performing operations believed to be impossible only decades ago, and has even been utilized to limit the development of prostate cancer in men.

Aeronautics is among the most recent industries to discover the benefits of gold, which also proved to have shielding properties against infrared radiation. Due to these properties, space shuttle construction companies use it to coat the interior of ships where heat sensitive equipments is stored, while aeronauts have the visor of the spacesuits coated on the interior with a 33% gold allow which protects their eyes against solar radiation.
