Liquid oxygen, commonly abbreviated LOX, is the liquid form of elemental oxygen. It is produced by cooling oxygen gas to its boiling point at standard pressure, which is -183°C (-297°F). LOX is pale blue, paramagnetic, and remains a cryogenic liquid under ordinary storage conditions. It has a density of about 1.14 g/cm³ at its boiling point and is a highly reactive oxidizer that can intensify fires.
LOX is produced industrially by fractional distillation of liquid air. In this process, air is compressed and
Common uses of liquid oxygen include rocket propulsion, where LOX serves as the oxidizer in combination with
Historically, the liquefaction of oxygen occurred in the late 19th to early 20th century, enabling practical
