Application

Ammonium pentaborate is an alkaline salt utilized in the creation of thin films by developing an oxide film which can inhibit corrosion of metals. It finds applications in the preparation of electrolytic capacitors, as a solvent for metallic oxides, as a flame retardant additive, in synthesis of nitrogen-doped ZnO particles, and in treatment of carbon nanotmaterials.
