Oxygen

Oxygen (O2) is a colorless, odorless, highly oxidizing gas.

Applications
Component in calibration gas mixtures for environmental monitoring systems and industrial hygiene gas mixtures; used for instrumentation in the petrochemical industry; used in first-aid treatment of emergencies such as suffocation and heart attack; in the treatment of patients with respiratory disorders; in anesthesia; and in hyperbaric oxygen chambers for treatment of carbon monoxide poisoning and gas gangrene.

Used as a zero gas for trace impurity analyses. Used in bomb calorimeters, specialized oxidation reaction detectors, and in chemical oxidation reaction studies.

Semiconductor: Chemical vapor deposition of silicon dioxide, especially for MOS gate oxides; thermal oxide growth; plasma etching; plasma stripping of photoresistors; carrier gas in certain deposition/diffusion operations.
