Compressed argon gas is allowed to expand, to cool the seeker heads of some versions of the AIM-9 Sidewinder missile and other missiles that use cooled thermal seeker heads. The gas is stored at high pressure. [49] Argon-39, with a half-life of 269 years, has been used for a number of applications, primarily ice core and ground water dating.
The gas used is usually inert, or of a nature that protects the integrity of the packaged goods, inhibiting unwanted chemical reactions such as food spoilage or oxidation. Some may also serve as a propellant for aerosol sprays like cans of whipped cream. For packaging food, the use of various gases is approved by regulatory organisations. [1]
The stages of blowing remove carbon by the combination of oxygen and carbon forming CO gas. 4 Cr (bath) + 3 O 2 → 2 Cr 2 O 3 Cr 2 O 3(slag) + 3 C (bath) → 3 CO (gas) + 2 Cr (bath) To drive the reaction to the forming of CO, the partial pressure of CO is lowered using argon or nitrogen. Since the AOD vessel is not externally heated, the ...
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.

A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
Claude's patents envisioned the use of gases such as argon and mercury vapor to create different colors beyond those produced by neon. For instance, mixing metallic mercury with neon gas creates blue. Green can then be achieved using uranium (yellow) glass. White and gold can also be created by adding argon and helium. [25]
Leon Wyczółkowski, A Game of Croquet (1892–1895), National Museum, Warsaw. Croquet (UK: / ˈ k r oʊ k eɪ,-k i / or US: / k r oʊ ˈ k eɪ /) is a sport [1] [2] which involves hitting wooden, plastic, or composite balls with a mallet through hoops (often called "wickets" in the United States) embedded in a grass playing court.
