Laser Synthesis of Oxide Nanopowders

Abstract:

Oxide nanopowders Y2O3, ZrO2, YSZ (Y2O3-stabilized ZrO2), Ce0.8Gd0.2O2 and Y2O3- Al2O3 compounds were prepared with the help of laser evaporation and subsequent vapor condensation in the flow of buffer gas. An efficient technology and setup to produce high purity weakly agglomerated nanopowders are demonstrated. The output rate, alteration of elemental composition, size distribution and crystalline structure of the nanopowders depending on parameters of laser radiation and buffer gas flow are reported.
