Influence of additives on the properties of spherical nickel particles prepared by ultrasonic spray pyrolysis
(Journal of Materials Research, 1999)
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, morphology, and formation mechanism of mullite particles produced by ultrasonic spray pyrolysis
(New York : Cambridge Univ Press, 1996)
Submicrometer spherical particles of mullite powder were synthesized by ultrasonic spray pyrolysis of emulsion and solutions, using tetra-ethyl-orthosilicate (TEOS) or silicic-acid and Al(NO3)(3) . 9H(2)O as initial ...
