Used primarily as a flux in aluminum smelting and welding processes, it helps lower the melting point of metal mixtures and improves the fluidity of molten aluminum. This enhances the efficiency of metal transfer and reduces energy consumption during production. It is also employed in the manufacture of refractory materials and ceramics due to its thermal stability. In some cases, it serves as a grain refiner in aluminum alloys to improve mechanical properties and surface finish. Additionally, it finds use in specialty glasses and enamel coatings for corrosion resistance.
