Ammonium pentaborate is a product resulting from the controlled reaction of ammonia, water, and boric acid.
Commercial and experimental applications of boron-based materials to improve both anodes and electrolytes indicate substantial benefits to batteries.
Ammonium pentaborate SQ, Optibor SQ (boric acid), and borax decahydrate SQ may be used in several different ways in the manufacture of both “wet” and “dry” types of electrolytic condensers or (more correctly) electrolytic capacitors.
Optibor is a pure, multifunctional source of boric oxide. Apart from borax pentahydrate, they are the most widely used industrial borate.
