Uses of Neon
- The reddish-orange coloured neon lights are used in making advertising signs. It’s also utilized in these types of lights generally when many other gases are needed to generate lights of different colours.
- Other uses of neon include lightning arrestors, high-voltage indicators, television tubes and meter tubes.
- Gas lasers are made with the help of neon and helium.
- The electronics industry uses neon singly or in mixtures with other gases in many types of gas-filled electron tubes.
- A mixture of helium and neon is used for respiration by marine divers in the sea since helium is less soluble in blood than nitrogen at high pressure.
