                                                                         Borax Pentahydrate

Features:

The Borax penta is a complex borate mineral that is found in playa lakes and other evaporite deposits. The basic structure of borax contains chains of interlocking BO2(OH) triangles and BO3(OH) tetrahedrons bonded to chains of sodium and water octahedrons. Most old mineral specimens of borax are chalky white due to a chemical reaction from dehydration. They have actually altered (at least on their surface) to the mineral tincalconite, Na2 B4O7-5H2O, with the loss of water. This kind of alteration from one mineral to another leaves the original shape of the crystal. Minerologists refer to this as a pseudomorph, or "fake shape", because the tincalconite has the crystal shape of the predecessing borax.

 

Borax is directly deposited in arid regions from the evaporation of water in intermittent lakes called playas. The playas form only during rainy seasons due to runoff from adjacent mountains. The runoff is rich in the element boron and is highly concentrated by evaporation in the arid climate. Eventually the concentration is so great that crystals of borax and other boron minerals form.

Characters:

a white, crystalline powder, colorless crystals or crystalline masses, efflorescent, soluble in water, very soluble in boiling water, freely soluble in glycerol.

Usage:

mainly used for glass and porcelain enamel industry. In glass industry, it can enhance transparency and heat-resistant property. In porcelain enamel products, it can make enamel not easy to fall off and with luster. it also widely used in pesticide, fertilizer, optics glass, glass fiber, colored metal as jointing agent, cohering agent for jewelry, printing and dyeing, detergent, refined gold, cosmetics, borax soap, antiseptic, antifreeze, and in pharmaceuticals as disinfectors etc. its also one of basic raw material for making other boric compound.
