Description
Boron Oxide (Glassy, Anhydrous), also known as Diboron Trioxide (B₂O₃), is the oxide of boron with the formula B₂O₃. It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty. It is also called boric oxide or boria. It has many important industrial applications, chiefly in ceramics as a flux for glazes and enamels and in the production of glasses.

Usage & Benefits
Usage and Benefits:
Glass: It is used as an agent to lower the fusing point and to increase the thermal expansion coefficient in glass production. Moreover, it improves the scratch resistance and acid resistance of glass and enhances its color and gloss properties.
Ceramics: Boron oxide is used in the production of ceramic and enamel glazes. Its functions are to regulate the coefficient of thermal expansion between the glaze and the material to be glazed; to ensure that the index of refraction of the glaze is high; to increase the mechanical properties and the scratch resistance of the glaze and to increase resistance against water and chemicals.
Boron chemicals: In the production of boron chemicals, it is used in the production of inorganic compounds such as boron hydrides, boron nitrides, and is used as a catalyst in the production of organic boron compounds such as boric acid esters.
Metallurgy: It is used as flux in the metallurgy industry as it is a good solvent for metal oxides.
Electric-Electronic: It is used in the production of Ga-As (Gallium-Arsenic) semiconductors.
