Abstract

Ionic conductors are important for many applications, including batteries, fuel cells, etc. Perovskite phases formed using Sandia Octahedral Molecular Sieves (SOMS) Na4(Nb/M)4O12•nH2O (M = transition metal) as precursors were studied. The synthesis of defect-filled perovskite phases started with the low temperature hydrothermal synthesis of metastable SOMS. SOMS had a wide composition space, allowing for the synthesis of perovskites outside equilibrium stability fields (large cation size mismatch). The SOMS precursor was then collapsed into the perovskite phase by calcining above 800°C. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
