Argon (Ar) is an inert gas of the noble gases (group 18), it is colourless, odourless and inert to other substances. It makes up 0.94% of the Earth’s atmosphere, the third most abundant atmospheric gas, with levels increasing gradually because radioactive potassium-40 turns into argon as it decays. Argon is 1.38 times heavier than air and can be obtained through the distillation of liquid air.

It has a number of uses but is well know for its use as an infill gas for double glazed units, where because of its density it improves the thermal performance bringing the temperature of the window closer to the temperature of the room. Whilst glass of a double glazed unit expands and contracts with temperature difference, the argon within the cavity doesn't, however it is generally accepted that the argon will normally leak from the unit at a rate of 1% each year, or more if the seals degrade or break.

Other uses of argon include the production of titanium and other reactive elements as it creates an inert environment preventing oxidisation and potential corrosion. Fluorescent tubes and low-energy bulbs also make use of argon with an electric discharge passing through the gas, generating UV light, the bulbs coating on the inside is activated by UV light and glows brightly.
