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.
