A graded material containing tetragonal, monoclinic, and pyrochlore phases are obtained when sintering at 1200\u00b0C and for 5 min holding time.

With the successful combination of the stabilizer coating technique and SPS, we achieve not only the stabilization of the tetragonal phase in the ceramics, but also good control of the grain size, by producing nanostructured ceramics with 40-70 nm grain sizes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this work, spark plasma sintering (SPS) of 10 mol% CeO 2-doped ZrO 2 nanocrystalline powders, obtained by a two-step synthesis procedure, allows the preparation of fully densified nanostructured ceramics.
