Depending on its purity, nitrous oxide (often called “laughing gas”) is widely used in the food, medical, and semiconductor industries.
Nitrous oxide may be used as an aerosol propellant in various fields:
-for whipped cream (because it improves the foaming characteristics of the cream), syrups, concentrates of coffee, chocolate and various flavours, sauces for grilled meats, vinaigrette etc. -pharmaceutical field
-cosmetics (perfumes, eau de cologne, hair spray, etc.)
-household products, paints and varnishes, insecticides
-aerosols for use at low temperature, such as de-icers, engine starting boosters, etc.

Applications

Semiconductors

High-purity nitrous oxide gas (≥5N) is mainly used in semiconductor, LCD, OLED manufacturing process. High purity nitrous oxide is an important raw material for PECVD process accumulation of SiO2 film, device anti-reverse penetration film, passivation membrane.

Medical

Nitrous oxide is commonly used as a general anaesthetic in both medical and dental surgeries. To be effective as an anaesthetic, nitrous oxide must be inhaled in relatively high concentrations mixed with air or oxygen.

Industrial

Nitrous oxide serves in industry as a leak detector for vacuum and pressurized enclosures, buried piping, etc.

Chemical

Nitrous oxide is used as an oxygen source in the chemical vapour deposition of silicon oxynitride layers.

Environment

Nitrous oxide is used in calibration mixtures for environmental control.

Racing cars

Nitrous oxide is used as an oxygen enrichment medium for high performance internal combustion engines (Drag racing)

Aviation

Nitrous oxide is used as raw material for the production of rocket fuel.
