Abstract
A method of inhibiting amorphous silica scale formation on surfaces in contact with industrial waters containing dissolved silicates is disclosed. The method involves treating the industrial waters with a boron compound which dissolves in or hydrolyzes in these industrial waters to give the orthoborate ion. The preferred boron compound is boric acid, its salts, or precursors.
