Bulk sodium tetraborate keeps metalworking shops, farms and glass plants running
Borax, chemically known as sodium tetraborate, remains one of the most versatile mineral compounds in industry thanks to its alkaline nature and reactivity with metals and acids. A 25 kg package is built for continuous consumption rather than occasional home use, serving metalworking shops, farms, glass and ceramic plants where raw material turnover is steady and substantial. This product belongs to the Acids, Salts, Alcohols, and Alkalis section, gathering inorganic compounds used across industrial and laboratory settings worldwide.
The largest global demand for borax comes from metalworking and soldering. Sodium tetraborate is used as a flux for soldering copper, brass, silver and steel, dissolving oxide films on metal surfaces, lowering slag melting temperatures and producing clean, strong joints. Jewelry workshops and metal fabrication plants purchase borax in bulk precisely because consumption during regular operations is high and batch consistency matters for repeatable results.
Glass and ceramics manufacturing rank second in importance. Borax is added to glazes, enamels and borosilicate glass formulations, reducing the melting point of the batch and improving thermal resistance of the finished product. In ceramic tile and sanitary porcelain production, sodium tetraborate helps achieve an even coating without cracking during firing.
The agricultural sector relies on borax as a boron source for crops suffering from micronutrient deficiency, particularly on sandy and calcareous soils. Foliar feeding solutions typically use around 1 to 3 grams per liter of water, though exact dosage depends on the crop and region, which is why agronomists prefer purchasing raw material in this volume to mix their own formulations.
In wood processing, sodium tetraborate serves as an antiseptic and fire-retardant treatment, reducing wood flammability and suppressing fungal growth and mold development, which is valued when treating timber, particleboard and packaging cardboard. Household chemical manufacturers use borax as a component in detergents, bleaching agents, laundry powders and dishwashing formulations, since the compound softens water and boosts the action of surfactants.
Cosmetic manufacturing applies borax in a limited way, mainly as a buffering agent and emulsifier when working with beeswax in cold cream and balm formulations, where formulators often pair it with supporting salts such as Sodium Citrate to regulate the acidity of the finished product. In food and flavor compositions, inorganic salts are sometimes combined with flavor enhancers like Sodium Glutamate, although this direction belongs to a related industry rather than direct borax use.
Sodium tetraborate dissolves best in warm water at 40-60 degrees Celsius, which is worth considering when preparing working solutions for production. Store the product in a dry area with tightly closed packaging, since the compound tends to cake when exposed to humid air. Compatibility with other salts in technological solutions, including Sodium hydrosulfite, is usually tested separately for each formulation, as reducing and alkaline components may interact with one another.
Fireproofing solution for textile and cellulose fabrics
Borax 10-hydrate 1200 g
Water 5000 ml
Boric acid 800 g
Dissolve
borax in hot water at around 60 degrees Celsius while stirring continuously
until fully clear, then add boric acid and continue mixing for another 10
minutes until the solution is uniform. Soak the fabric or cellulose material in
the solution for 15 to 20 minutes, wring out excess liquid, and dry flat at
room temperature away from direct heat sources before further processing or
storage.
