White powder crystal, specific weight 1.69-1.73, hardness 2-2.5. It is soluble in water, in soluble in alcohol and the solution indicating wealk baicity. When heated to 350-4.00° C, it loses the crystal water and changes into waterless borax, which feature sterilizing. It will do harm to one's health taking orally.

Uses: An important material for glass, enamel, ceramics, nonferrous mentl, metallurgical industry, etc. It can be used as a micro-element manure and disinfectant in agriculture, and it is also widely used in pharmaceutical industry. Borax is also a basic raw material for boride and high energy boron hyduide fuel.

Usages   Glass  and  glass  fiber   In  the  manufacture  of  insulating  glass  wool,   textile  fiberglass  and  borosilicate  glass  (heat-resistant  glass,   electric  light  source  glass,   glass  burner,   drugs,   cosmetics  bottles,   hollow  beads,   optical  lenses,   sealed  glass)  and  other  areas,   as  provided  by  oxidation  boron  materials.   Ceramic  and  enamel  glazes   Pentahydrate  borax  (Neobor)  increase  ceramics'   (such  as  tiles,   tableware,   ceramics  and  enamel  device,   etc. )    compressive  strength,   abrasion  resistance  and  chemical  resistance.   As  the  thermal  expansion  coefficient  of  B2O3  on  the  control  of  making  the  glaze  to  adapt  the  line  to  improve,   but  also  can  reduce  the  melting  temperature  of  B2O3,   prevent  loss  through.   Makes  the  product  more  smooth  and  more  perfect. Other  applications   Fertilizer,   detergent,   bleach  detergent,   flame  retardant,   antirust,   binder,   stabilizer,   emulsifier  etc.
