Krypton is a rare inert and non-toxic gas that does not have a specific taste, smell, or colour. It is obtained as a by-product in the form of krypton-xenon concentrate when separating air at industrial plants.

Krypton is used to create high-powered lasers in rocket and aerospace engineering.

Due to its high density and weight, krypton can ensure thermal insulation and soundproofing. It is used to fill windows to improve the energy performance of buildings.

Krypton low heat conductivity allows for using it in lamps and car headlights. The light of krypton in terms of colour is close to sunlight and it is more powerful compared to argon or nitrogen.
