Crystal structure of the Sr6Nb4ZrO18 slab perovskite-like compound

Abstract

Abstract. The Sr6Nb4ZrO18 niobatozirconate has been synthesized from the Sr5Nb4O15 four-layer perovskite and the SrZrO3 perovskite at T = 1670 K by ceramic technique. Crystal structure of the Sr6Nb4ZrO18 compound has been studied by the X-ray powder diffraction method. It was shown that crystal structure of the Sr6Nb4ZrO18 (a = 0.5687 (1)
