Abstract

This report deals with the production and characteristics of Y₂O₃ -stabilized ZrO₂ (YSZ), A1₂O₃+YSZ, GDC, Nd:Y₂O₃ and Nd:YAG nanopowders prepared by evaporation of the materials with the help of a pulse-repetitive CO₂ laser. The design of a setup for the nanopowders production, scheme and characteristics of the original CO₂ laser excited by a pulse-periodic combined discharge are reported. For YSZ; Al₂O₃+YSZ, Nd:Y₂O₃, Nd:YAG the output rate was 15-25 g/h, for GDC ~ 50-75 g/hour, the energy consumption 30-40 (W*h)/g and 8-15 (W*h)/g, respectively. Data for the nanopowders specific surface, size distribution, the results of X-ray phase and structure analysis, as well as the results of luminescence analysis are discussed. The analysis of the obtained results showed that two main factors that determine the output rate of the nanopowders synthesis are the type of material evaporated and the mean laser radiation power. The mean size of the nanoparticles doesn't depend on the type of material.
