Aside from jewelry, other ornaments, gold coins and gold bars, most of us are unfamiliar with other uses of gold. Clearly, it has been primarily employed in medicine. Advanced technology has also found that gold is very useful in fields related to astronomy and computers alike.
Dentists have found that they have not really been able to use iron as a dental cap and fillings, and have found the perfect alternative to gold. Iron gets rusty and it is difficult to make what patients need. Gold, on the other hand, is very flexible and does not require complex equipment to work with. Also, many people like it because its color is visually appealing and not allergenic. For the same reason and despite the higher cost, dental bridges and other orthodontic equipment are also made of gold alloys.
Gold has also been used in the treatment of some ailments. Some types of cancer are treated by implanting radioactive gold isotope particles in the tissue. A strange disease known as lagophthalmos, or not being able to close the eyes completely, is cured by inserting a small amount of gold into the upper eyelid to act as a weight. The weight of the metal combined with the gravitational pull will completely close the eyelids. Rheumatoid arthritis is treated by injection of a weak solution of sodium orothioglucose or orothiomelate.
In the case of electronics, gold is still used as a reliable connector and conductor. Smaller parts, especially computers, require conductors that do not rust, and gold has all these specifications. This facilitates accurate data transfer at an extremely fast speed.
Aerospace engineers have found an ally in this precious metal in their equipment. Gold-plated polyester film on different parts of the spacecraft helps stabilize the spacecraft’s temperature by deflecting infrared radiation and prevents the parts from absorbing sufficient amounts of heat. The lubrication of the mechanical parts of the spacecraft is crucial so that the finest and thinnest film of gold can be worked between them – this provides the necessary amount of lubrication of the essential moving parts. Another advantage of gold over organic lubricants is that gold can withstand strong radiation in outer space and cannot break down. Solar radiation in space is harmful to astronauts’ eyes and skin, and they protect their wearing visors with a fine layer of gold.
The future still sees many innovations that bring gold into the game and prove that this metal is not just for aesthetic purposes. This is why the need for gold is never less. This is why prices are so high regardless of other financial factors that affect many products. Why it comes to selling gold for cash; There is no shortage of buyers.
