摘要：
Sintering of nanocrystalline (nc) monoclinic yttrium oxide (Y2O3) was studied in the homologue temperature range of 0.4-0.7T(M). Samples were isostatically consolidated at super high pressure (SEP), up to 1.8 GPa. The combined effects of consolidation pressure and sintering temperature on the properties and microstructure are explored. The physical properties of the samples, mainly elastic modulus follow in general the density changes, or the interparticle contact area, but are also affected by sintering temperature. The effect of compaction pressure and sample density on the phase transition is studied and discussed. (C) 2013 Elsevier Ltd. All rights reserved.
