Original Abstract

Zirconia nanoparticles were densified by pressureless sintering and spark plasma sintering (SPS). The evolution of relative density and pore size distribution in powder compacts during these sintering processes were compared. It was found that pore size increase was suppressed during SPS and in this way the densification was facilitated. The combined sintering process (low-temperature presintering by SPS followed by pressureless sintering) was performed to confirm the advantage of low-temperature SPS technique (referred to as SPS warm pressing).
