  2. Argon - Wikipedia

    en.wikipedia.org/wiki/Argon

    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. For some of these processes, the presence of nitrogen or oxygen gases might cause defects within the material.

  3. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    The flue gas system uses the boiler exhaust as its source, so it is important that the fuel/air ratio in the boiler burners is properly regulated to ensure that high-quality inert gases are produced. Too much air would result in an oxygen content exceeding 5%, and too much fuel oil would result in the carryover of dangerous hydrocarbon gas.

  4. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

  5. Argonium - Wikipedia

    en.wikipedia.org/wiki/Argonium

    Argonium (also called the argon hydride cation, the hydridoargon(1+) ion, or protonated argon; chemical formula ArH +) is a cation combining a proton and an argon atom. It can be made in an electric discharge , and was the first noble gas molecular ion to be found in interstellar space.

  6. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    Hydrogen, being the lightest existing gas (7% the density of air, 0.08988 g/L at STP), seems to be the most appropriate gas for lifting.It can be easily produced in large quantities, for example with the water-gas shift reaction or electrolysis, but hydrogen has several disadvantages:

  7. Argon compounds - Wikipedia

    en.wikipedia.org/wiki/Argon_compounds

    Argon compounds, the chemical compounds that contain the element argon, are rarely encountered due to the inertness of the argon atom. However, compounds of argon have been detected in inert gas matrix isolation, cold gases, and plasmas, and molecular ions containing argon have been made and also detected in space.

    U.S. prosecutors asked a federal appeals court on Wednesday to pause their bid to revive the criminal case accusing President-elect Donald Trump of illegally handling classified documents, citing ...

  9. Penning mixture - Wikipedia

    en.wikipedia.org/wiki/Penning_mixture

    A very common Penning mixture of about 98–99.5% of neon with 0.5–2% argon is used in some neon lamps, especially those rated for 120 volts. The mixture is easier to ionize than either neon or argon alone, and lowers the breakdown voltage at which the tube becomes conductive and starts producing light.
