Phase Stability of Rare-Earth Based Mixed Oxides in Nano-Regime: Role of Synthesis

Abstract:

Synthesis plays an important role in the phase stabilization of unusual compounds. Of late, preparation of metastable compounds has gained a tremendous momentum due to unusual properties exhibited by them. In this article, we will discuss how by mere change in certain parameters of the reaction a metastable phase can be isolated using a soft chemical route. Surface energy induced stabilization are also observed wherein enhanced stability of the mixed oxides are observed in the nano-regime of the compound.
