Liquid oxygen (also LOx, LOX or Lox in the aerospace, submarine and gas industry) is a form of the element oxygen. It has a pale blue color and is strongly paramagnetic and can be suspended between the poles of a powerful horse shoe magnet. Liquid oxygen has a density of 1.141 g/cm³ (1.141 kg/L) and is cryogenic (freezing point: 50.5 K (−222.65 °C), boiling point: 90.19 K (−297.33 °F, −182.96 °C) at 101.325 kPa (760 mmHg). In commerce, liquid oxy...

Liquid oxygen (also LOx, LOX or Lox in the aerospace, submarine and gas industry) is a form of the element oxygen. It has a pale blue color and is strongly paramagnetic and can be suspended between the poles of a powerful horse shoe magnet. Liquid oxygen has a density of 1.141 g/cm³ (1.141 kg/L) and is cryogenic (freezing point: 50.5 K (−222.65 °C), boiling point: 90.19 K (−297.33 °F, −182.96 °C) at 101.325 kPa (760 mmHg). In commerce, liquid oxygen is classified as an industrial gas and is widely used for industrial and medical purposes. Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation. Liquid oxygen has an expansion ratio of 861:1 at 68 °F (20 °C); and because of this, it is used in some commercial and military aircraft as a source of breathing oxygen.
LOX used in space rockets (and probably in aerospace) is a mixture of liquid oxygen with up to 25% liquid ozone and several additives to stabilize this liquid oxyidator.
Due to its cryogenic...
