Used as a key ingredient in buffer solutions for biochemical and analytical applications due to its ability to maintain stable pH levels. Commonly found in eye wash solutions and contact lens care products for its mild antiseptic and buffering properties. Employed in the manufacturing of fiberglass, ceramics, and glazes, where it acts as a flux to lower melting temperatures and improve thermal shock resistance. Utilized in metallurgy as a soldering and welding flux to prevent oxidation and promote metal flow. Applied in wood preservation and fire retardant formulations for its ability to inhibit combustion and resist fungal decay. Found in household cleaning products, including laundry detergents and automatic dishwasher detergents, for its water-softening and stain-removal capabilities. Used in educational and recreational settings as a cross-linking agent in the preparation of slime and other polymer-based materials. Serves as a precursor in the synthesis of other boron-containing compounds used in industrial and research applications.
