Boric acid, also called hydrogen borate, boracic acid and orthoboric acid is a weak, monobasic Lewis acid of boron often used as an antiseptic, insecticide, flame retardant or neutron absorber. 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.
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. 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. Boric acid is used in the production of the glass in LCD flat panel displays.
In electroplating, boric acid is used as part of some proprietary formulas. One such known formula calls for about a 1 to 10 ratio of H3BO3 to NiSO4, a very small portion of sodium lauryl sulfate and a small portion of H2SO4. Boric acid, mixed with borax (sodium tetra borate decahydrate) is used for fire retarding agent of wood by impregnation. It is also used in the manufacturing of ramming mass, a fine silica-containing powder used for producing induction furnace linings and ceramics. It is also used in the manufacture of talcum powder & some pharmaceutical (pharma) applications.
