Borax Pentahydrate is the refined form of natural sodium borate and has the chemical formula Na₂B₄O₇.5H₂O. Composed of boric oxide (B₂O₃), sodium oxide, and water, it is a mild, alkaline salt, white and crystalline, with excellent buffering and fluxing properties.
Available in crystalline (granular) form, Borax Pentahydrate is an important multifunctional source of B₂O₃, particularly for processes in which the simultaneous presence of sodium is beneficial.
