    ►Origin of Boric acid 



        Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and


    acidum boricum, is a weak, monobasic Lewis acid of boron, which is often


    used as an antiseptic, insecticide, flame retardant, neutron absorber, or


    precursor to other chemical compounds. It has the chemical formula H3BO3


    (sometimes written B(OH)3), and exists in the form of colorless crystals or a


    white powder that dissolves in water. When occurring as a mineral, it is called





      ► Occurrence


        Boric acid, or sassolite, is found mainly in its free state in some volcanic


    districts, for example, in the Italian region of Tuscany, the Lipari Islands and


    the US state of Nevada. In these volcanic settings it issues, mixed with steam,


    from fissures in the ground. It is also found as a constituent of many


    naturally occurring minerals – borax, boracite, ulexite (boronatrocalcite) and


    colemanite. Boric acid and its salts are found in seawater. It is also found in


    plants, including almost all fruits.


    Boric acid was first prepared by Wilhelm Homberg (1652–1715) from borax,


    by the action of mineral acids, and was given the name sal sedativum


    Hombergi ("sedative salt of Homberg"). However borates, including boric


    acid, have been used since the time of the ancient Greeks for cleaning,


    preserving food, and other activities.

    Water insoluble ≤0.06%








         Boric acid may be prepared by reacting borax (sodium tetraborate


    decahydrate) with a mineral acid, such as hydrochloric acid:


    Na2B4O7·10H2O + 2 HCl → 4 B(OH)3 [or H3BO3] + 2 NaCl + 5 H2O


    It is also formed as a by product of hydrolysis of boron trihalides and




    B2H6 + 6 H2O → 2 B(OH)3 + 6 H2


    BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)




     ►Application in Industry




    1. Monofilament fiberglass



       The primary industrial use of boric acid is in the manufacture of monofilament


    fiberglass usually referred to as textile fiberglass. Textile fiberglass is used to


    reinforce plastics in applications that range from boats, to industrial piping to


    computer circuit boards.




     2. Combination with denatured alcohol



    In the jewelry industry, boric acid is often used in combination with denatured


    alcohol to reduce surface oxidation and firescale from forming on metals during


    annealing and soldering operations.



    3. LCD flat panel displays



       Boric acid is used in the production of the glass in LCD flat panel displays.
