The porous ZrO2 ceramics was prepared by spark plasma sintering (SPS) at 520 °C. A dense closed micro-cellular ceramic structure was fabricated with micron Al90Mn9Ce1 alloy powders clading by 10 wt% ZrO2 nano-powder. SEM image showed that the thickness of ceramic cell wall was 1.0 - 2.0 μm. After deep corrosion with 10% HCl, an integrity nanocrystalline ZrO2 porous sample was obtained. Based on the experimental results, the transient spark plasma sintering mechanism of micron-nano mixing powder was also studied.

The results of the study of the spark plasma sintering of SmS-based ceramics have been presented. The dependence of the microstructure and phase composition of ceramics on the temperature of spark plasma sintering was studied by using SEM, EDX and XRD. It is shown that, at a sintering temperature of 1200 ° C, dense, non-porous ceramics are formed and the phase composition of the sintered ceramics is close to that of the initial powder.

Spark-Plasma Sintering (SPS) involves rapid heating of powder by electric current with simultaneous application of external pressure. Numerous experimental investigations point to the ability of SPS to render highly-dense powder products with the potential of grain size retention. The latter ability is of significance for the consolidation of nano-powder materials where the grain growth is one of the major problems. A model for spark-plasma sintering taking into consideration various mechanisms of material transport is developed. The results of modeling agree satisfactorily with the experimental data in terms of SPS shrinkage kinetics.
