The gas that is normally used is argon, or a mixture of argon and nitrogen.
A gas is needed that
• helps prevent the evaporation of white-hot tungsten
• does not react with white-hot tungsten
• will not form an electric arc inside the bulb
Argon is the cheapest of the noble gases because it forms nearly 1% of the atmosphere, and is a major by-product in the production of liquid nitrogen.
