Application:Â
Â
A. Household products
Borax is used in various household laundry and cleaning products. Borax is also present in some tooth bleaching formulas.
B. Buffer
Sodium borate is used in biochemical and chemical laboratories to make buffers, e.g. for gel electrophoresis of DNA, such as TBE or the newer SB buffer or BBS (borate buffered saline) in coating procedures. Borate buffers (usually at pH 8) are also used as preferential equilibration solution in DMP-based crosslinking reactions.
C. Flux
A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also used mixed with water as a flux when soldering jewelry metals such as gold or silver. It allows the molten solder to flow evenly over the joint in question. Borax is also a good flux for 'pre-tinning' tungsten with zinc - making the tungsten soft-solderable.
Â
Â
Besides, it is widely used as solder of galss fibre and non-ferrous metal; as binder of jewelry; for refining of gold; as basic raw material for the production of boron compound. It is also widely used in the fields of cosmetics, furtilizer, borax soap, preservative, antifreeze, chemical disinfectant as well as metallurgy, steel, machinery, war industry, cutter, papermaking, electronic tube, chemicals, spinning, ect.
