Nitric oxide, with the chemical formula NO.In industry, nitric oxide is typically produced through the high-temperature combustion reaction of nitrogen and oxygen. This reaction often occurs in gas-fired power plants, furnaces, or industrial combustion equipment operating at elevated temperatures. Nitric oxide can also be generated through the reaction of ammonia and air in the presence of a catalyst. In industry, nitric oxide is used as an oxidizer, catalyst, and disinfectant, among other applications.

Applications

Environmental

Nitric oxide is used in the preparation of standard mixtures employed in controlling atmospheric pollution. Mixtures of nitric oxide, often in the ppm, or even ppb, range are used to test and calibrate pollution and emission control analyzers.

Semiconductors

Nitric oxide is used for oxidation of semiconductors in the electronic industry.

Medical

Nitric oxide mixtures have been used therapeutically in humans for several medical indications.
