What is the primary use of krypton gas?
Medical imaging
Flash photography
Neon signs
Gas lasers
Krypton gas is used as a filler in energy-efficient windows. In double or triple-pane windows, the space between the panes is filled with an insulating gas to improve the window's energy efficiency. Krypton gas is one of the gases used for this purpose due to its high thermal resistance and low thermal conductivity. The gas helps to reduce heat transfer through the window and improves the insulating properties of the window. This results in a window that provides better insulation and is more energy-efficient than traditional single-pane windows.
Krypton gas is also used in some types of fluorescent lamps and as a filler gas in some types of gas lasers, but its primary use is definitely in energy-efficient windows.
