Anwendungen

Boric acid is a precursor material for other boron compounds. A dilute water solution of boric acid is usually employed as a mild antiseptic and eyewash. Boric acid is employed in leather manufacture, electroplating and cosmetics. It is involved in the production of monofilament fiberglass which finds applications in boats, industrial piping, LCD flat panel displays and computer circuit boards. It is in combination with sodium tetraborate decahydrate (borax) and is used as a welding flux by blacksmiths. The mixture of boric acid and silicone oil is useful in the production of silly putty.

Bemerkungen

Store in cool place. Moisture sensitive. Incompatible with potassium and acid anhydrides.
