Abstract

Nanophase Technologies Corporation (NTC) employs a new physical vapor synthesis technique to manufacture ceria-based mixed rare earth oxide nanomaterials. The mixed rare earth oxide nanoparticles are nonporous, dense, discrete crystals. The compositions are solid solutions that remain thermally stable to above 1050°C.

Ceria is an active oxygen storage material. Doping ceria with other rare earth metals enhances the thermal stability of nanocrystalline particle size and increases the oxygen storage capacity (OSC). The mean particle size and OSC of ceria-based mixed rare earth oxides are presented as a function of particle composition, morphology, and thermal history.

These materials are commercially available and are being engineered for several applications including oxygen storage catalysts and polishing materials.
