[ДСТУ] Crystal structure of the Sr6Nb4ZrO18 slab perovskite-like compound / Y. A. Titov et al. French-Ukrainian Journal of Chemistry. 2015. Vol. 3, no. 2. P. 65—71. DOI: 10.17721/fujcV3I2P65-71 (date of access: 25.07.2026).
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) nm, c = 4.146(1) nm, R-3m space group) belongs to the Ba6Nb4TiO18-type with five-layer perovskite-like structure. The crystal structure features of the Sr6Nb4BIVO18 compounds (BIV = Ti, Sn, Zr) has been analyzed. The correlation between composition and crystal structure features for all Sr6Nb4BIVO18 (BIV = Ti, Sn, Zr) compounds, which leads to destruction slab perovskite-like structure has been revealed.
