Abstract

The influence of the non-cavitational powerful ultrasonic action (PUA) on the particle size distributionand lattice parameters of crystallites of zirconia andalumina dry nanopowders have been studied. Theultrasonic treatment occurred in the acoustic waveguidewith a cavity, filled by a dry nanostructured powder(NP). The PUA of different power was used to variousdry NP: ZrO2-8%Y2O3 (TZ-8Y, TOSOH); ZrO2-3%Y2O3 (TZ-3YS, TOSOH); ZrO2-3%Y2O3 (PCZY,Siberian Chemical Plant, SCP); Al2O3 (UDPO, SCP). Itwas found that non-cavitational PUA influences thelattice parameters and average agglomerate sizes of dryzirconia and alumina NP. There are extreme PUApowers at which extreme values of the latticeparameters and average agglomerate sizes arecorrelated. The crystal structure of the TZ-3Y (synthesisby spray-drying) is more stable against PUA than PCZY(plasma-chemical synthesis).
