The design and characteristics of a setup for producing oxide nanopowders
are reported. Y2O3 - stabilized ZrO2 (YSZ),
Al2O3+YSZ and CeGdO nanopowders are
prepared by target evaporation with a pulse-periodic CO2-laser, followed by vapor
condensation in air stream. Average laser radiation power is 600 W, pulse power ~ 10
kW. The output rates of YSZ and Al2O3+YSZ nanopowders are 15-20 g/h, and CeGdO
nanopowder - 55-60 g/h. The grain mean size in the powders is 15nm. Data for the
powder characteristics, as well as results of X-ray phase and structure analysis, are
reported. The reasons of higher CeGdO output rate are discussed.
