The glass industry is the largest user of borax. The addition of a certain amount of borax to the glass production can enhance the thermal stability of the glass, increase the transmittance of ultraviolet rays, and improve the transparency and impact resistance of the glass. In recent years, boric acid has also been widely used in the manufacture of glass fibers, which are not only important raw materials for the production of FRP, but also new materials for construction, machinery and naphthalene industry.
