Physical Properties
  • Colorless and Odorless: Liquid oxygen is colorless and odorless.

  • Liquefies at Low Temperatures: Oxygen, which is a gas at room temperature, becomes liquid at -183 degrees.


  • Fractionation: Air is distilled at low temperatures to separate it into components such as oxygen and nitrogen.

  • Electrolysis: Water can be split into hydrogen and oxygen using electric current.


Areas of Use
  • Medical Applications: Used in hospitals, surgical interventions and respirators.

  • Industrial Processes: Used to enhance oxidation in welding of metals, glass production and other industrial processes.

  • Space Research: Used as rocket fuel in space exploration and as a source of oxygen in space shuttle systems.

  • Energy Production: Oxygen is used for energy production in many combustion processes.

  • Chemical Industry: Used in chemical synthesis and processes.


General Properties
  • Oxygen is essential for cellular respiration of living organisms. Cells produce energy by burning oxygen.

  • The respiratory system ensures that oxygen is taken into the body and carbon dioxide is removed.


  • High Oxygen Concentrations: Liquid oxygen can cause high oxygen concentrations, which when combined with flammable materials can increase the risk of fire.

  • Cooling Effect: Has a cooling effect on skin contact and should be handled with care.


Liquid oxygen plays an important role in many industries and medical applications. Especially in the medical field, it is an indispensable resource for respiratory devices and surgical interventions. It has a wide range of applications from space exploration to energy production.
