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 shock resistance and chemical durability, commonly used in labware and cookware.

Serves as a precursor in the synthesis of boron-based chemicals and ceramics, including boron nitride and boron carbide, which are used in high-strength, heat-resistant materials.

Employed in the manufacture of fiberglass and insulation materials due to its ability to enhance strength and reduce melting temperatures.

Utilized in some electronic applications, such as in semiconductors and dielectric materials, where controlled boron content is required.

Acts as a catalyst or catalyst support in certain organic reactions and industrial chemical processes.
