Nitrogen Dioxide Supplier to Northern Illinois

This brownish, toxic, corrosive, liquefied PurityPlus® gas has several commercial uses, and Weldstar Specialty Gases can deliver it quickly to Northern Illinois customers.

Nitrogen Dioxide (NO₂) is an atmospheric contaminant that results when fossils fuels come in contact with excess oxygen and ignite; at flame-inducing temperatures, the oxygen not burned with the fuel reacts with the nitrogen from the air to form nitric oxide (NO) and, with more oxygen and heat, is further oxidized to NO₂. For commercial use, Nitrogen Dioxide is achieved in the oxidation of ammonia at well-moderated temperatures in a steam-rich environment.

Nitrogen Dioxide’s most common use is in rocket motors, more accurately in its dimerized state as N₂O₄ (Nitrogen Tetroxide, NOM 4). In this state, it is reacted with hydrazine to spark 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 place motors in orbiting satellites that may require relocation over time. NO₂ is also employed as an oxidizing agent in organic synthesis and in select applications as a sterilizing atmosphere.

In specialty gas applications, NO₂ is often a component in calibration gases for environmental emission and industrial hygiene monitoring.
