Description

Description générale

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

Boric acid can have a large scale use in glass industry as flame retardant, in buffer solutions.
Boric acid finds uses in several areas; such as

• In glass fibres, to enhance its resistance and color
• In glazing ceramic wares
• As a condensing agent, chemical intermediate and as a precursor for preparation of borates and other boron based compounds
• As a water coolant in nuclear reactors
• In electrolytic condensers and capacitors 1
