Crystal Structures of CaLa8Ti9O31 and Ca2La4Ti6O20 Determined from Powder Diffraction Data.
The ceramic materials of CaLa8Ti9O31 and Ca2La4Ti6O20 were synthesized using the solid-state reaction method. The crystal structures were determined from powder diffraction data using direct space methods. Like in similar compounds of the general formula AnBnO3n+2, the title compounds are composed of perovskite-like slabs, separated by oxygen-rich layers, where Ca or La occupy the A site.
