Abstract

A new method for the synthesis of complex metal oxides, based on hydrodynamic cavitation, was used to prepare pure phase, nanostructured solid-state materials. The continuous process afforded a wide variety of metal oxides in grain sizes of 1-10 nm. Catalysts, ceramics, superconductors, piezoelectrics, and zeolites were prepared by cavitational synthesis. The method enabled the synthesis of fine particles of metals and metal oxides supported on high surface area supports such as silica, and the synthesis of fine particles of cubic zirconia without ion modification.
