THE SYNTHESIS AND CHARACTERIZATION OF SOLID-STATE MATERIALS PRODUCED BY HIGH-SHEAR HYDRODYNAMIC CAVITATION

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