Abstract

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.
