Characteristics of High Purity Oxygen
Colourless and odourless gas. Many materials burn in Oxygen that do not normally burn in air. Reduces the flash point temperature and increases the combustion speed.
Applications
Many oxidation reactions in the chemical industry use pure oxygen rather than air in order to benefit from higher reaction rates, easier product separation, higher yields or smaller equipment size.
High purity oxygen is used for the formation of silicon dioxide and metal oxide, as an etchant for photoresist.
Oxygen is also used in conjunction with hydrogen to fuel torches for welding, brazing, glass blowing and tube sealing for a variety of electronic components.
Mixed with other gases, oxygen serves in the production of breathable atmospheres.
Oxygen is also widely used as a calibration gas and as a medical gas.
