Ideal spherical nonagglomerated Ni particles (mean diameter 0.62-1.12 mu m) were prepared by ultrasonic spray pyrolysis of NiCl2 aqueous solution in the presence of 0.1 mass% of Pd, Cu, or Ni in an H-2-N-2 atmosphere at ...

Synthesis of ultrafine spherical TiO2 particles was achieved by using ultrasonic spray pyrolysis and nanoparticles of TiO2 (approximate to 2.5nm) as a precursor. The size distribution and morphology of TiO2 particles ...
