Usage | Typical Application |
Argon has several desirable properties: | Argon is a chemically inert gas. Argon is the cheapest alternative when nitrogen is not sufficiently inert. Argon has low thermal conductivity. Argon has electronic properties (ionization and/or the emission spectrum) desirable for some applications. |
Industrial processes | Argon is used in some high-temperature industrial processes where ordinarily non-reactive substances become reactive. For example, an argon atmosphere is used in graphite electric furnaces to prevent the graphite from burning. |
Scientific research | Liquid argon is used as the target for neutrino experiments and direct dark matter searches. |
Preservative | Argon is used to displace oxygen- and moisture-containing air in packaging material to extend the shelf-lives of the contents |
Laboratory equipment | Argon may be used as the inert gas within Schlenk lines and gloveboxes. |
Medical use | Cryosurgery procedures such as cryoablation use liquid argon to destroy tissue such as cancer cells. |
Lighting | Incandescent lights are filled with argon, to preserve the filaments at high temperature from oxidation. |
