General description

Boric acid is a weak monobasic acid, it accepts OH- ions, hence is a Lewis acid. In boric acid, B is sp2 hybridized, forming a planar triangle structure.The principal oxide of boron, B2O3, is obtained as a vitreous solid by dehydration of boric acid at red heat.

Application

•Glass manufacturing: Used in the manufacture of glass fibers to enhance strength and color.
•Ceramics: employed in glazing ceramic wares for improved durability and aesthetics.
•Chemical Intermediate: Acts as a precursor for borates and other boron-based compounds.
•Nuclear Reactors: Utilized as a water coolant and neutron absorber in nuclear applications.
•Electrolytic Capacitors: Used in the production of electrolytic condensers and capacitors.
