The work aim was the quantitative comparison of compressibility parameters of different dry nanostructured ceramic powders using coefficients of the compaction equation in dimensionless form. Pressing characteristics of different nanopowders manufactured by diverse methods were investigated: ZrO2-Y2O3; Al2O3-MgO; Al2O3; (Ba,W)TiO3; (Ba,Sr,Ca)TiO3; Pb(Zr,Ti)O3. Dry compaction was carried out by the common uniaxial pressing and under powerful ultrasound action (PUA). It was shown that the dimensionless compaction equation describes the compaction diagrams of dry ceramic nanopowders with high reliability and its coefficients allow to characterize quantitatively the compressibility of different powders. The production methods of nanopowders even the same chemical composition determine the pressing characteristics of dry cold compaction. YSZ nanopowders manufactured by plasma-chemical or chemical synthesis have essentially different compressibility parameters. PU-action during dry pressing shows the most efficiency for ceramic nanopowders having metastable structure and not uniform morphology.
