METHOD FOR PREPARING PARTICULATE METAL OXIDE MATERIALS
A method for preparing metal oxide and ceramic oxide nano- and microparticulate materials is described herein. The method comprises irradiating a precursor material with high energy pulsed-light flashes in an oxygen-containing atmosphere. The precursor materials comprise thin films, fibers, or particles of subnano-, nano-, or microscale dimension, which are composed of metal ions dispersed in an amorphous or partially crystalline polymer matrix in a ratio necessary to form target metal oxide or ceramic oxide when reacted with oxygen (i.e., the precursor material does not include any metal oxide phase). The irradiation of the precursor material in an oxygen-containing atmosphere decomposes and removes the polymers and anions from the precursor, and also oxidizes the metal ions within the precursor materials to form metal oxide or ceramic oxide particulates.
