B2O3 68% Min Pure Borax Powder Safety Colorless White Pyrobor

Powder

►Description 

    1. Anhydrous borax is also called  borax, dehydrated borax,pyrobor,  it's an

important compound because it can be used to produce sodium borohydride which

is one of the best chemicals that carry hydrogen and releases hydrogen upon

hydrolysis. 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.

     2. 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.

►Origin

  1. 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).

   2.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

aporous 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.

   3. 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.
