Description

Metaboric Acid is an inorganic boron compound with the chemical formula HBO₂. This versatile chemical intermediate is valued for its role in the synthesis of specialty borates and as a precursor in advanced material manufacturing. It serves as a critical raw material for industries including glass and ceramics, flame retardants, and metallurgy, where precise boron content and purity are essential.

Application

• Glass & Ceramics Manufacturing: Acts as a fluxing agent and a source of boron oxide (B₂O₃) to modify thermal expansion and improve chemical durability in specialty glasses, enamels, and glazes.
• Flame Retardant Systems: Used as a component in the formulation of halogen-free flame retardants for polymers, textiles, and wood products, leveraging boron's char-forming and smoke-suppressing properties.
• Metallurgy & Metalworking: Employed in fluxes for soldering, brazing, and welding, and as an additive in metal surface treatment baths to enhance coating adhesion and corrosion resistance.
• Chemical Synthesis: Serves as a key precursor for producing other high-purity boron compounds, such as boron nitride, boron carbide, and various metal borates.
• Laboratory & Research: Utilized as an analytical reagent and a standard in various chemical and material science research applications.
