Uses of Boric Acid

 

Industrial

Used in Nuclear Power plants to slow the rate of fission. In the jewelry industry to is used in combination with denatured alcohol to reduce surface oxidation. Also used in the production of glass for flat panel displays. Boric Acid is also used in electroplating. Used in the manufacture of remming mass – a fine silica powder used for the production of induction furnace linings and ceramics.

 

Insecticide

Used to control insects – cockroaches, termites, ants etc.
Safe for use in households and kitchens.

 

Preservation

In combination as an insecticide, Boric Acid can prevent and destroy wet and dry rot.
