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.
