Nitrous Oxide
Nitrous Oxide is a colorless, odorless, non-flammable gas.
Nitrous Oxide
Formula: N2O
CAS No: 10024-97-2
Nitrous Oxide (N2O) is a colorless, non-flammable gas with mild oxidizing properties, used across medical, semiconductor, and industrial applications. It is widely recognized for its role as an anesthetic gas, as well as for its ability to support controlled oxidation reactions in manufacturing environments.
In semiconductor processing, nitrous oxide is used as an oxidizing and nitriding agent, contributing to the formation of high-quality silicon dioxide and silicon oxynitride films. Its controlled reactivity enables precise tuning of dielectric properties in advanced device fabrication.
Applications include:
Applications (Main Text)
- Used as an anesthetic and analgesic gas in medical and dental procedures.
