Pure Anhydrous Borax Powder,
Crystal Granular Anhydrous Borax Powder,
1330-43-3 Anhydrous Borax
Anhydrous borax have mang names , such as borax, dehydrated borax,pyrobor.
1. it's an important compound because it can be used to produce sodium
borohydride whichis one of the best chemicals that carry hydrogen and releases
hydrogen upon hydrolysis.
2. In addition, a product processing unit based on the method of powder
atomization is designed and manufactured. After manufacturing works, a set of
experiments is performed and anhydrous borax is produced.
3. As a result, anhydrous borax (Na2B4O7) is obtained including the following
constituents as mass percentages; 68% B2O3 and 30% Na2O. The difficulties in
the post-processing stage are overcome by the use of powder atomization unit and
in the mean time, continuity in production is also established.

►How it came
Anhydrous borax is made by burning or fusing hydrated borax. It thus contains
little or no water of crystallization (conversation ratio of .53 compared to hydrated
decahydrate borax) and does not rehydrate under normal storage conditions.
Anhydrous borax is water soluble, but considerably less so than raw borax (in
aqueous solution it can provide slow release of boron). This material does not puff
or swell during melting (minimizing loss of powder in kilns with strong drafts), and
melts easier (the swelling in other forms can create a porous state with an
insulation factor that slows melting). Anhydrous borax is an excellent glass former,
it does not puff or swell during melting thus fewer production problems result.
This material is used as a source of B2O3 in the manufacture of many different
types of borosilicate glass, including heat and chemical resistant glasses,
illumination glasses, optical lenses, medical and cosmetic containers, hollow
microspheres and glass beads. It has a higher bulk density and melts more rapidly
than raw forms of borax. It also provides a source of sodium.
