Product Description
95% UN NO1458 white powder sodium borate use for corrosion
inhibitor water treatment
►Origin of Borax decahydrate
Borax was first discovered in dry lake beds in Tibet and was imported via the
Silk Road to the Arabian Peninsula in the 8th Century AD.Borax first came into
common use in the late 19th century whenFrancis Marion Smith's Pacific Coast
Borax Company began to market and popularize a large variety of applications.
Borax is a component of many detergents, cosmetics, and enamel glazes. It
is used to make buffer solutions in biochemistry, as a fire retardant, as an anti-
fungal compound, in the manufacture of fiberglass, as a flux in metallurgy,
neutron-capture shields for radioactive sources, a texturing agent in cooking, as
a precursor for other boron compounds, and along with its inverse, boric acid, is
useful as an insecticide.In artisanal gold mining, the borax method is sometimes
used as a substitutefor toxic mercury in the gold extraction process. Borax was
reportedly used by gold miners in parts of the Philippines in the 1900s.
►Product description
Borax Decahydrate is the refined form of natural sodium borate. 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 powder or
granular form.Borax Decahydrate is an important multifunctional source of B2O3,
particularly for processes in which the simultaneous presence of sodium is
beneficial.Borax decahydrate , also known as sodium borate, is an important
boron compound, a mineral, and a salt of boric acid.Powdered borax is white,
consisting of soft colorless crystals that dissolve easily in water.

►Application
Corrosion inhibition
Borax Decahydrate is incorporated in many aqueous systems requiring corrosion
inhibition. It protects ferrous metals against oxidation and finds use in the
manufacture of automotive and engine coolant formulations, and various water
treatment chemicals.The high solubility of Borax Decahydrate in ethylene glycol
makes it especially useful in car antifreeze formulations. Borax Decahydrate
neutralizes the acidic residue resulting from the decomposition of ethylene glycol
and minimizes the rate of oxidation at the surface of the metal. Aqueous solutions
of Borax Decahydrate have replaced chromates in railroad and other diesel engine
coolants.
