Boric Acid

Boric acid, the formula is H3BO3. It is a pure, multifunctional source of boric oxide and the most widely used in boron industry. It is theoretically composed of boric oxie and water.

Boric acid also called hydrogen borate, boracic acid, orthoboric acid and acidum boricum, is a weak acid of boron often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. Crystalline in composition, white in appearance, it can be used as granules or as a powder. Both forms are stable under normal conditions, free flowing and easily handled by means of air or mechanical conveying. In solution, the are mildly acidic.

Boric acid mainly used in glass and glass fiber (Heat resistant, Fiber glass, Pyrex, Illumination, Glass instrument, Medical or cosmetic containers, hollow or solid micro-spheres, optical glass, sealing glass), Frits, Glazes and enamels, Metallurgy, Flame retardancy, Chemical reactions.
