    ►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

     

    sassolite.

     

     

      ► 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%

     

     

     

     

     ►Preparation

     

     

         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

     

    diborane

     

    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.
