Gold Uses in Industry
knowledge of the commercial uses of gold enables a savvy investor to make a judgement on the future demand for the metal and in conjunction with other criteria such as the erosion of the purchasing power of a currency, political factors, gold hoarding or selling off by governments, the technical picture, etc.etc., can make the decision to be long, short or stay out of the market until a more favorable opportunity occurs.
Medicine
Gold is non toxic and biologically benign, an excellent conductor of electricity, virtually indestructible, easy to shape and flatten and can be drawn out into microscopically thin strands known as bonding wire.
The current demand for gold in dentistry is about 60 tonnes annually having recovered from a decline to circa 48 tonnes in 1987.
Rapid and ongoing developments in the use of lasers incorporating gold coatings are making dramatic progress in the treatment of cancers, sealing battlefield wounds in the field, emergency injury treatments in hospitals and previously inoperable heart conditions and tumors.
Lasers reliant on gold are used in delicate eye and brain surgery where absolute accuracy is essential.
As these power wheelchairs are used outdoors and often exposed to extremes of temperature and weather, the use of gold in essential components is necessary to minimize breakdowns and the possible life threatening consequences.
Hi-Tech Electronics
Gold plays an essential part in every one of the millions of computers and peripherals that are produced worldwide every year. Gold is refined to 99.999 % pure and is drawn out to a wire only one hundredth of a millimetre in diameter.
This bonding wire is used to connect the semi-conductors and circuits. It is used on circuit boards and to make the contacts when using the keyboard.
TVs, VCRs and DVD Players
The circuits are connected by fine lines of gold to the micro-electronic circuit chips that change the incoming signals into a TV picture and sound.
Space
As the exploration of space continues so more and more uses for gold are being developed. Silicon wafers containing gold wafers protect on board computers in spacecraft from bombardment by heavy ions in space and allows monitoring and adjustments of the computers by ground control.
State of the art sophisticated and intricate gold circuitry allowed color pictures and chemical analysis of the surface of Mars to be transmitted back to earth.
The tonnage of gold used annually in the electronics industry amounts to approximately 150 tonnes with
Japan being the major electronics manufacturer and accounting for over 45% of gold consumption, followed by The US with circa 30%.
The ever increasing speed of advances in technology suggests that even more uses will be found for the unique properties of gold and the consequential increase in consumption by the industrial sector alone.
