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. Serves as a buffering agent in certain electroplating baths and finds use in the synthesis of boron-containing compounds for specialty glass and ceramic production. Its thermal stability and boron content make it suitable as a precursor in the preparation of boride materials and in some agricultural formulations as a micronutrient source.
