Abstract
A disordered three-dimensional perovskite phase SrTa2-xNbxO6 (x = 0, 0.2, 0.4) is formed by topochemical dehydration of acid-exchanged Ruddelsden Popper compounds K2SrTa2-xNbxO7. The metastable perovskite is a stoichiometric precursor to the structurally unrelated, stable tetragonal tungsten bronze phase. Dehydration occurs at 350−400 °C and conversion to the tungsten bronze phase occurs about 800 °C.
