Oxygen

Oxygen ,O₂  is used in various fields, including steel, melt-cutting, medical, sewage and industrial wastewater treatment, and also plays a role in the development of next-generation technologies, including space exploration and biotechnology。

Applications

Semiconductors

High purity oxygen is used for the formation of silicon dioxide and metal oxide, as an etchant for photoresist, and in mixtures with halocarbons for etching silicon.

Electronics Industry

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 such as reed relay switches.

Environmental

Injecting oxygen into sewage treatment plants accelerates the decomposition of sewage.

Chemical

Oxygen is used for chemical synthesis. Oxygen is used as an oxidizer.

Industrial

Oxygen is used to supplement or replace air in burners used in many different industries in order to obtain increased temperatures. Typical applications are found in the steel, non-ferrous, glass and concrete industries amongst many others. Oxygen is used for flame sealing of glass ampuls for finished products for the pharmaceutical industry and the chemical industry.

Food

In the food industry, oxygen is used in the transportation of live fish and seafoods. Oxygen is used in some cases for modified atmosphere packaging (MAP) of food stuffs. It is used either pure or in mixtures with carbon dioxide and/or nitrogen.

Aviation

Liquid oxygen is used in liquid oxygen explosives, and as a comburent in space propulsion.

Medical

Oxygen is used in medical gas mixtures.
