Gold is one of the most precious metals in the world and has always been a symbol of wealth and luxury. It has been used for centuries for various purposes, such as jewelry, gold coins, dentistry, biology and production. Extracts a high price on the market and the gold price is an important part of the world economy.Gold has several characteristics that make a metal useful for many purposes other than to create beautiful jewelry. It 's a good electrical conductor and is very malleable and ductile.
Moreover, good corrosion resistance and good thermal conductivity as well. All these features make it indispensable for use in a variety of electronic products.The importance of gold in the room can not be denied. It 'used in a number of means of all spacecraft and it would be wrong to say that without the use of gold, the man could not visit the moon. When building a spaceship, it is important to note that once launched into space, there is minimal possibility of repair or lubrication. Thus, highly reliable materials for use in their production, as gold.
Gold used in circuits equipped with the probe, because it is a good conductor. Also, many parts of space vehicles are equipped with a polyester film coated with gold, which reflects the infrared radiation and contributes to the temperature inside the vehicle. Otherwise, the vehicle to absorb too much heat, making it difficult to work. Gold plates with a thickness of about 0.15 mm are used as radiation included if in fact reflect the sunlight gold is also used as a lubricant between the various mechanical parts of the spacecraft.
If a different lubricant was used, it would exceed the radiation in space and is evaporated. Why gold is very malleable and ductile, it is easy to thin sheets of gold used as a lubricant between the parties metal.Gold is also used in helmets worn by astronauts. A very thin layer of gold in the electrolyte to the harmful rays of the sun visor prevents the penetration and returns. In this way, it protects the vision of astronauts.Gold is important for space travel and tours, that space is increased over the years, so the demand for gold.
