Can gold become a gas?

Any element can become a gas; you just need to heat it past its boiling point. For gold, that’s 2,856 degrees Celsius (5,173 degrees Fahrenheit), which is hotter than the temperature in an arc furnace so it’s difficult to just boil a bar of gold. But you can create small amounts of gold gas by bombarding it with a high-energy beam of electrons in a vacuum. This knocks atoms of gold free from the solid mass and they’ll fly around and coat anything in the vacuum chamber. Electron beam vapour deposition is used to create very thin gold coatings for the electronics, medical and space industries. Gold coatings can also be used as a lubricant in machinery.
