Oxygen(O2)

High-purity oxygen (O₂) for healthcare, metal processing, chemical oxidation, and life support systems.

Oxygen is a colorless and odorless gas at room temperature, existing as the most common elemental form of oxygen. It is slightly soluble in water, with about 30 mL dissolving per liter. Liquid oxygen appears sky blue, while solid oxygen forms blue crystals. At room temperature, oxygen is relatively inactive and does not readily react with many substances. However, at elevated temperatures, it becomes highly reactive and can directly combine with a wide range of elements, due to its high electronegativity. Oxygen serves as a critical gas for medical and respiratory applications, as an oxidizer in metal processing (steelmaking, welding, cutting), as a reactant in chemical synthesis, and as an essential component in life support and aerospace systems. It is typically transported as a liquefied compressed gas or in high-pressure cylinders.
