Mass Spectroscopy Analysis

In this work, structural characterization of selected perovskite-type compounds from Ba[Formula: see text]Gd[Formula: see text]Zr[Formula: see text]SnxInyO[Formula: see text] group is given, including high temperature XRD measurements. An evidence of water incorporation into the crystal structure of the materials in a form of OH[Formula: see text] is discussed on a basis of thermogravimetric studies, with mass spectroscopy analysis of the gases released from samples on heating/cooling. As expected, oxygen non-stoichiometry was found to play a dominant role concerning possibility of water uptake. In addition, a rather strong affinity of the materials towards CO2 was documented, which seems to be a problem concerning possible application of the compounds as proton conducting solid electrolytes.

High temperature reactions of BaCO3/MnO/Er2O3 (3:1:1) led to single crystals of Ba3ErMn2O9. The product shows the structure of the hexagonal precious metal oxides Ba3LnRu2O9, but crystallizes with orthorhombic symmetry, space group C122v-Cmc21, a = 5.823 Å, b - 10.099 Å, c = 14.409 Å; Z = 4. The crystal structure is characterized by ErO6 octahedra, Mn2O9 face shared double octahedra and Ba2+ within cuboctahedral and anticuboctahedral coordination by O2-, respectively. In contrast to precious metal oxides the Mn-Mn distances inside the Mn2O9 double octahedra are elongated
