Nanoparticles can have different form but predominantly are obtained as solid grains. The properties of many materials based on these nanopowders are relatively well known. Using ultrasonic spray pyrolysis (2,6 MHz) nanopowders composed of hollow ball-shaped grains were obtained. The diameter of grains vary in the range 2 - 400 nm. The obtained nanopowder materials were metallic (Ru, Ag, Pd, Ag-Pd, Ag-Rh), ceramic (Al2O3, Al2O3-Cr2O3, CeO2, CeO2-ZrO2) as well as composite (cermetals: NiO-Au, CeO2-ZrO2-Pt and CeO2-ZrO2-Au).
