Borax Pentahydrate 99.9% Technical Grade, granular. High purity and concentration, Available in small or large packaging.
Grade: Technical; Formula: Na2B4O7. 5 H2O
Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. Powdered borax is white, consisting of soft colorless crystals that dissolve easily in water.
Uses: Heat-resistant glass; porcelain enamel; detergents; fertilizers’ leather; photography; bleaches; paint; laboratory reagent.
Additional Description
Toxic by inhalation, noncombustible
Applications:
- Borax can inhibit the growth of wood-damaging fungi and help to protect wood products against pests. That means wood treated with Borax can be used in construction in areas that would otherwise be off limits because of rot or termites.
- The fire-retardant capabilities of borax products make them a perfect choice for housing and wiring insulation.
- Ultra-high strength steel, made with borax, is much harder than other metals and makes cars lighter and less vulnerable to corrosion.
- Borax used in the production of ceramic frits help to create robust glazes and enamels, for longer-lasting tiles, roofs, silos, appliances, and more.
- Boron is an essential nutrient for crop growth. Boron supplementation can enable farmers to increase crop yield and quality, which can help to reduce bottom-line food costs.
- Borax is used as flux for soldering and welding (including forge welding and welding electrodes)

Sodium Tetra Borate, Decahydrate (Borax), 99.9%
Sodium Tetra Borate, Decahydrate (Na₂B₄O₇·10H₂O), commonly known as Borax, is a 99.9% pure, technical-grade boron compound widely used across industries. This white powder or fine granular substance consists of soft, colorless crystals that dissolve easily in water. Borax is a key ingredient in heat-resistant glass, porcelain enamel, and detergents and is used in flux soldering, forge welding, fertilizers, photography, and laboratory reagents. With a boron oxide (B₂O₃) content of 37.74% and minimal impurities, Borax ensures consistent performance for industrial applications. Noncombustible and toxic by inhalation, it must be handled with care. Note that Borax is restricted from food, nutritional, and carpet applications. This essential material is available in small and bulk packaging to suit diverse requirements.
