Borax Decahydrate is the refined form of natural sodium borate and has the chemical formula Na2B4O7.10H2O. 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) or powder form, Borax Decahydrate is an important multifunctional source of B2O3, particularly for processes in which the simultaneous presence of sodium is beneficial.
