Used as a flux in metallurgy to remove oxides and improve metal flow during welding and brazing.

Key component in the production of borosilicate glass, known for high thermal resistance and chemical durability.

Serves as a precursor in the synthesis of boron-based chemicals and ceramics, including boric acid, boron nitride, and other compounds used in refractories and electronics.

Employed in the manufacture of enamels and glazes for ceramics due to its low melting point and stability.

Utilized in nuclear reactors as a neutron absorber in control rods and shielding materials.

Added to fertilizers in trace amounts to supply boron, an essential micronutrient for plant growth.

Applied in semiconductor manufacturing as a boron source for doping materials, and in high-temperature refractories for enhanced thermal stability in compositions.
