Nitrogen Dioxide Supplier to Sioux Falls

This brownish, potentially deadly, corrosive, liquefied PurityPlus® gas is actually used in a number of commercial applications, and A-OX Welding Supply makes it readily available to Sioux Falls customers.

Nitrogen Dioxide (NO₂) is an atmospheric contaminant that results when fossils fuels come in contact with excess oxygen and ignite; at high combustion temperatures, the oxygen not set ablaze with the fuel reacts with the nitrogen from the air to form nitric oxide (NO) and, in combination with increased oxygen and heat, is further oxidized to NO₂. For commercial application, Nitrogen Dioxide is achieved by the oxidation of ammonia at controlled temperatures in a steam-rich environment.

Nitrogen Dioxide’s most frequent use is in rocket motors, more appropriately in its dimerized state as N₂O₄ (Nitrogen Tetroxide, NOM 4). In this state, it is reacted with hydrazine to provide propulsion. These liquefied gases may be stored for exceptionally long periods in space given that they’re not cryogenic fluids and thus pose no threat of excessive venting from boil-off. They are used to position motors in orbiting satellites that may need repositioning at some future date. NO₂ is also useful as an oxidizing agent in organic synthesis and in special applications as a sterilizing atmosphere.

In specialty gas applications, NO₂ is commonly a factor in calibration gases for environmental emission and industrial hygiene scrutiny.
