    Widely Use Pure Borax Powder Crystal Granular 201.22 Molecular



    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.
