Nitrogen Dioxide Supplier to Fresno

This brownish, toxic, corrosive, liquefied PurityPlus® gas has several commercial uses, and Fresno Oxygen & Welding Supplies/Barnes Welding Supply can deliver it quickly to Fresno customers.

Nitrogen Dioxide (NO₂) is produced as an atmospheric contaminant by the combustion of fossil fuels in excess oxygen; at high combustion temperatures, the oxygen not burned with the fuel reacts with the nitrogen from the air to form nitric oxide (NO) and, in combination with more oxygen and heat, is further oxidized to NO₂. For commercial application, Nitrogen Dioxide is created via the oxidation of ammonia at well-moderated temperatures in a steam-rich environment.

Nitrogen Dioxide’s largest use is in rocket motors, more appropriately in its dimerized state as N₂O₄ (Nitrogen Tetroxide, NOM 4). In this form, it is reacted with hydrazine to provide propulsion. These liquefied gases offer the advantage of long-term storage in space without excessive venting from boil-off, as neither are cryogenic fluids. They are used in positioning motors in orbiting satellites that might need to be relocated over time. NO₂ is also employed as an oxidizing agent in organic synthesis and in certain applications as a sterilizing atmosphere.

When it’s employed in specialty gas applications, NO₂ is frequently a factor in calibration gases for environmental emission and industrial hygiene scrutiny.
