A process of manufacturing an oxide material for use in an oxygen generator. A quantity of dry zirconia particles is blended with Barium Peroxide particles and thereafter heated in a nitrogen atmosphere until the Barium Peroxide melts and coats the zirconia particles. The Barium Peroxide coating is subsequently decomposed to Barium Oxide. The Barium Oxide coated zirconia particles are allowed to cool and then passed through a grinder to produce a uniform particle size for oxide material.
