It is the most common form of sodium borate used in industry.
Consisting of white granules or crystalline powder, it is slightly
alkaline in solution. The advantages of Borax Pentahydrate are the lower cost of
transportation, handling, and storage of a more concentrated
product. It is stable under normal, free-flowing conditions, and is easily
controlled by mechanical or pneumatic conveying.
1. Granular borax, also known as sodium borate, sodium tetraborate,
or disodium tetraborate. 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 cross-linking agent in slime, as an alkali in
photographic developers, as a precursor for other boron compounds,
and along with its inverse, boric acid, is useful as an
2. Borax pentahydrate is generally written as Na2B4O7•5H2O.
Powdered borax is white, consisting of soft colorless crystals that
dissolve in water.
3. Usually a white powder contains colorless, odorless and salty
crystals. The specific gravity is 1.73. All crystal water is
lost at 350-400°C. Soluble in water and glycerol, slightly soluble
in alcohol. The aqueous solution is strongly alkaline.
4. For borax pentahydrate we import it from Turkey and American.
Their brand name is ETiMADEN and THREE ELEPHANT.
