Description

Sodium Oxide (Na2O) is a highly reactive inorganic compound widely utilized in industrial and laboratory settings. This white crystalline solid is composed of two sodium cations (Na+) and one oxygen anion (O2−), offering exceptional alkalinity and reactivity with water to form sodium hydroxide (NaOH). With a CAS number 1313-59-3, it is available in high-purity grades (≥80%) for precision applications. Sodium oxide serves as a key precursor in glass manufacturing, ceramics, and chemical synthesis due to its ability to modify silicate structures and act as a fluxing agent. Proper handling under inert conditions is essential due to its hygroscopic and corrosive nature.

Sodium oxide is primarily employed as a flux in glass production, reducing melting temperatures and improving workability. In ceramics, it modifies glaze compositions to enhance thermal stability. Laboratories use it as a strong base or desiccant, though handling requires strict moisture exclusion. It also acts as a precursor for sodium-based catalysts and specialty chemicals.
