Abstract
Nanopowders are composed of elementary particles (crystallites) of sizes smaller than 20 nm. Their heat treatment at lower temperatures than is the case with classic powders results in polycrystals of very small grain sizes which possess enhanced mechanical properties. Although numerous methods of producing nanopowders were elaborated, serious processing problems are still encountered, mainly due to the friction between powder particles. It follows that dry pressing of such powders does not lead to satisfactory results. In the present work this is investigated using nanopowders in the yttria-zirconia system. A method for their synthesis under hydrothermal conditions is described. The effect of the two forming methods on the powder behavior during sintering, dry pressing and pressure filtration, is shown.
