Gold is universally known for its diverse nature and properties. We all are familiar with the use of gold for its investment and ornamental value. Apart from these well-known uses, gold is also used as a medicine and in some industries.
Gold as a metal is so malleable and ductile that it can be beaten into huge thin sheets, or turned into very long and thin wires. It is for this reason that it is the most favourite metal of jewellery designers. Not only this, gold is used as an ideal material in some specific areas of Fine Arts like sculpture.
Pure gold is very soft; it can be twisted into any shape with human hands. It is alloyed with different metals or substances to retain its shape and to harden its texture. It can be mixed with silver, copper, nickel and cobalt etc. to put it to various uses.
Gold is an excellent conductor of electricity. It is used as a conductor in electronic machines like computers, lap tops, cell phones, calculators etc. It can transmit digital information to various components of a computer system within milliseconds. The computer industry depends upon gold for the manufacturing of its connectors.
Gold as a metal does not oxidize; hence, it never rusts or corrodes. This is the reason why, million years old archaeological finds, made of gold, are found in their original form, even after thousands of years. The pharaohs of Egypt were famous for burying their dead with the gold that belonged to them.
Gold has been widely used for its medicinal properties since ages. The science of dentistry promoted the use of gold in the making of crowns. Initially, it was thought that this is done just for its aesthetic appeal. But now, it is known that gold has disinfectant properties. The gold crown protects teeth from further decaying or damage; and these last longer than crowns made of other substances.
Gold is used in medicine for the treatment of Rheumatoid Arthritis. It is also used in the detection of cancerous cells in the body. Even surgical equipments and machinery have gold in them for its conducive and non-reactive properties.
If man was able to explore space, it was with the help of gold. The exterior of the spaceships is made with gold plated polyester films. Gold can reflect the infrared radiations, and help in controlling the temperature of the inside of the space craft. It is also used in the mechanical parts of the spaceships as a conductor and connector.
The glass industry also relies upon gold in the manufacturing of climate-control glasses that are used in buildings and houses. Gold is either spread inside the glass or coated on the surface to reflect the solar radiation. This way, the temperature of the building remains controlled during summer and winter, thereby saving a lot of energy that is otherwise spent on air conditioning. Hence, gold is also used in conserving energy.
