摘要：

Nanoparticles Of ZrO2 (n-ZrO2) synthesized by the inert gas condensation technique were consolidated by sinter-forging, which is a pressure-assisted sintering process. It was found that there is a threshold stress below which there is only a small contribution to densification by the applied pressure. The value of the threshold stress depends on grain size and the effect is explained on the basis of driving forces for sintering. The grain size in the fully dense n-ZrO2 samples was 45 nm.
