 25kg bag packing secure payment amorphous elemental pure boron for military-industrial

PRODUCT DESCRIPTION

 

product description :  

 Anhydrous borax, also known as sodium tetraborate, α orthorhombic crystal melting point of 742.5 ℃. Density 2.28, β orthorhombic crystal melting point of 664 ° C. Density is 2.75, traits of white crystalline or colorless glassy crystals, strong moisture absorption, it dissolves in water, glycerol, slowly dissolved in methanol, can form a concentration of 13-16% of the solution, the aqueous solution was weakly alkaline, insoluble in alcohol. Borax is heated to 350 ~ 400 ℃ obtain anbydrous borax. Put it in the air, it will change to borax decahydrate or 25kg bag packing secure payment pure boron by absorbing moisture

Product Uses

 

APPLICATION

 

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.

D.Small-scale mining

Borax is replacing mercury as the preferred method for extracting gold in small-scale mining facilities. The method is called the borax methodand is used in the Philippines.
