Water treatment chemical powder sodium tetraborate uses of

corrosion inhibitor CAS NO 1303-96-4

 ►Origin of sodium tetraborate

   1. sodium tetraborate 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.

   2. Borax first came intocommon use in the late 19th century whenFrancis

Marion Smith's Pacific Coast Borax Company began to market and popularize a

large variety of applications.

  3. 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

       Sodium tetraborate 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.

►Features 

 Water insoluble,Pro-environment,Insect-proofing .

 ►Application

Corrosion inhibition

    sodium tetraborate 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.
