What is Borax Decahydrate?
Borax Decahydrate (Na₂B₄O₇·10H₂O), also known as Sodium Tetraborate Decahydrate or simply Borax, is a naturally occurring boron mineral and salt of boric acid. It appears as a white crystalline powder or granules and is one of the most important boron compounds in industrial use. The decahydrate form contains ten water molecules per formula unit, making it the most common commercially available form of borax.
Polychem Industries supplies Borax Decahydrate to detergent manufacturers, glass and ceramic producers, agricultural companies, and industrial chemical users across India and internationally. Its versatile alkaline and fluxing properties make it indispensable across a wide range of industrial applications.

|---|---|---|---|---|
| Industrial Grade | White Crystalline Powder / Granules | 99.5% | Industrial | Detergents, glass, ceramics, metallurgy |
| Technical Grade | White Crystalline Powder | 99% | Technical | Agriculture, wood preservation, fire retardants |
Applications & Uses
Detergents & Cleaning Products
A key ingredient in laundry detergents and household cleaners as a builder, water softener, and stain remover. Borax boosts the cleaning power of surfactants and helps remove tough stains including grease, wine, and blood.
Glass & Fibreglass Manufacturing
Used as a flux in glass manufacturing to lower the melting temperature of silica and reduce thermal expansion. Widely used in borosilicate glass, laboratory glassware, fibreglass insulation, and optical glass production.
Ceramics & Glazes
Used as a flux in ceramic glazes and enamels to lower firing temperatures, improve gloss, and enhance the adhesion of glazes to ceramic bodies. Produces smooth, bright glaze surfaces.
Agriculture & Fertilisers
Used as a micronutrient source of boron in fertilisers for crops that are boron-deficient. Boron is essential for cell wall formation, pollination, and seed development in plants.
Wood Preservation & Fire Retardant
Used as a wood preservative to protect against fungal decay, termites, and other wood-boring insects. Also used as a fire retardant treatment for timber and cellulose-based materials.
Metallurgy & Welding
Used as a flux in metallurgy for soldering, brazing, and welding of metals. Cleans metal oxide films and prevents reoxidation during high-temperature joining processes.
