Abstract

Five-layer niobatozirconate Sr6Nb4ZrO18 has been synthesized by the ceramic technology (presynthesized reagents — four-layer Sr5Nb4O15 + perovskite SrZrO3, T = 1670 K), and its layered perovskite-like structure (LPS) is determined by the method of X-ray powder diffraction. It is found that the LPS of Sr6Nb4ZrO18 belongs to the Ba6Nb4TiO18-type structure. The parameters of the elementary cell of Sr6Nb4ZrO18: a = 0.5687(1) nm, c = 4.146(1) nm, space group R−3m, the value of the reliability factor RB is equal to 0.055. The peculiarities of Sr6Nb4BIVO18 (BIV = Ti, Sn, Zr) LPS are analyzed, and the correlations composition — constitution of LPS have been established.
