How It Compares
Within the perovskite oxides class.
Unlike the highly stable and widely utilized BaTiO3 or the robust perovskite structures like LaAlO3 and LaFeO3, Na2Sn2O3 exists in a metastable state. While many of its siblings in the perovskite class are prized for their structural longevity and well-defined phase diagrams, this compound offers a more complex, transient landscape for researchers investigating the limits of perovskite stability.
