Abstract

A reversible phase transformation process to convert bulk polycrystalline Y2O3 into the nanocrystalline state is described. It involves a forward phase transformation from cubic-to-monoclinic under a high pressure followed by a backward phase transformation from monoclinic-to-cubic under a lower pressure. Further work is underway to establish the optimal processing parameters (pressure-temperature-time) to achieve the finest possible nano-grain size in the fully transformed material.
