BORAX DECAHYDRATE
BORAX DECAHYDRATE
Sodium Tetra Borate Decahydrate
Na2B4O7.10H2O
Available as granular, powder and crystals (Lumps)
Stability
Sodium tetra borate decahydrate is stable under ordinary conditions but exposed to dry air or elevated temperatures it tends to lose water of crystallization. The basic chemical composition or properties are not changed thereby,

Usage
Borax is used for dissolving casein, starches, dextrines, shellac, natural gums and in the emulsification of waxes. It is thus an important component of many types of adhesives and coating and of a variety of cosmetic preparations. Its power to protect ferrous metals against rust results in its use in corrosion inhibitor formulations and contributes to its value as a lubricant carrier coating in drawing steel wire. The affinity of fused borax for metal oxides is the reason for its use as a flux in brazing and welding, metal refining and in the manufacture of glass, vitreous enamels and ceramic glazes. Some of the major uses are given below:
| Glass | Adhesives | Aluminium Detergent |
| Textiles | Paints | Preborates |
| Leather | Enamels | Ceramics |
| Casein Solvent | Abrasives | Timber preservation |
| Weed Control | Photography | Soaps and detergents |
| Laundry | Glues | Wax Polishes |
| Cosmetic | Pharmaceuticals |
Borax is used, as a straight micronutrient fertilizer, in boronated fertilisers, in micronutrients mixture formulations, in pesticides, for coating granular fertilisers and to develop plant resistance to insect, pests and diseases.
