Used as a flux in the metal industry, particularly in soldering and welding processes, by lowering the melting point of impurities and facilitating smooth melting.

Used as a flame retardant in wood-based materials and textiles due to its ability to form protective char layers upon heating.

Also applied in corrosion inhibition for metal surfaces, particularly in cooling water systems, and used in water treatment and coolant oils to control pH and prevent corrosion.

Serves as a buffering agent in certain electroplating baths.

Popular in the ceramics and glass industries to control material properties such as heat resistance and expansion.

Used as a precursor in the synthesis of other boron-containing compounds for the chemical industry and specialty materials, including boride materials.

Additionally, incorporated in certain fire retardant formulations to enhance fire spread inhibition efficiency, and used in some agricultural formulations as a micronutrient source.
