White crystals or vitreous. a orthorhombic crystal, relative density 2.28, melting point 742.5℃. B orthorhombic crystal, relative density 2.75. Melting point 664℃. Strong hygroscopicity. Soluble in water, slowly dissolved in methanol, can form a concentration of 13%~16% of the solution. Sodium Tetraborate Anhydrous is an anhydrous substance obtained when borax is heated to 350~400℃, When placed in the air, It can absorb moisture and become borax decahydtate or borax pentahydrate.
Sodium Tetraborate Anhydrous (CAS: 1330-43-4) has been mainly used in the manufacturing of high-quality glass, optical glass, glaze of pottery and porcelain, glaze of enamel, detergent, bleaching agents, cleaning agents, flame retardants, rust inhibitors, and caking agents.
Sodium Tetraborate could be also used as the carrier of the lubricant used in metal wiredrawing, the stabilizer of refractory material and skeleton former, the coated fluxing agent in metallurgy, the retarder of cement and concrete, the buffer of pH value in water systems and emulsifier of paraffin.
Sodium Tetraborate is also a raw material for the manufacture of optical glass, enamel and enamel. It can also be used to make artificial gems and fluxes. When borax melts, it becomes a colorless glassy substance and is used to manufacture special optical glass.
Medically used as a preservative. Chinese medicine is used as a heat-clearing and antidote.
In the chemical industry is the raw material for the manufacture of a series of boron compounds.
It is also used to make buffer solutions in biochemistry.
