Abstract:

This invention is directed to the use of zirconia, ZrO2, or ZrO2 combined with a boron compound, such as boric acid, H3BO3, or ammonium pentaborate, NH4B5O8, as fire retardants, for example in polymers such as commodity and engineering polymers, to fire retardant materials containing such a fire retardant and to methods for making materials fire retardant by use of such fire retardant agent.
