Depending on its purity, nitrous oxide (often called “laughing gas”) is widely used in the food, medical, and semiconductor industries.
Jinhong Gas has greatly improved the purity and production capacity of nitrous oxide through continuous technological updates, and is one of the outstanding suppliers in the semiconductor field.
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.
Nitrous oxide is obtained most commonly by the thermal decomposition of ammonium nitrate. It may also be obtained by controlled reduction of nitrites or nitrates, by the slow decomposition of hyponitrites, or by the thermal decomposition of hydroxylamine.
Jinhong recycles the exhaust gas, purify and refine it to get high-purity nitrous oxide, the key point is to control the content of CO2 and moisture before the gas entering into rectifying tower.
The annual output of Jinhong Gas's 5N5 N2O gas has exceded 9,000 tons.
| Gas | Nitrous Oxide |
| CAS No. | 10024-97-2 |
| Purity | ≥99.5% |
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.
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.
Nitrous oxide serves in industry as a leak detector for vacuum and pressurized enclosures, buried piping, etc.
Nitrous oxide is used as an oxygen source in the chemical vapour deposition of silicon oxynitride layers.
Nitrous oxide is used in calibration mixtures for environmental control.
Nitrous oxide is used as an oxygen enrichment medium for high performance internal combustion engines (Drag racing)
Nitrous oxide is used as raw material for the production of rocket fuel.
