|What is Gold used for?|
|Question Date: 2013-02-27|
Gold has a variety of uses, including
applications in jewelry, finance, computers,
dentistry, electronics, and medicine. Gold is
used as a conductor in computers and other
electronic devices because it is an efficient
conductor of low voltages and does not corrode
easily. It has historically been used as a
filling material for cavities in the dental
industry. It also has been found to have some
applications in medicine for the treatment of
various kinds of arthritis, cancer; and is used
in many medical devices as well.
Gold is valuable because it is resistant to
chemical damage (such as corrosion or
oxidation), soft, and both electrically and
thermally conductive. Because it is soft, it can
be made into a variety of shapes, or spun into
wire. This is important for making dental
implants, or for making electrical wiring.
Gold is useful in electronics: like copper
and silver, gold is an outstanding conductor of
electricity, but unlike copper or silver, gold
never tarnishes, making it ideal to use in
environments where corrosion is a problem. Gold
is also used to coat other metals in order to
protect them from corrosion.
