  • Reduction of the strontium titanate doped by Ytrium ceramics observed by X-ray photoemission spectroscopy method

    Dane Badawcze
    open access

    Ytrium-doped strontium titanate (YSTF) ceramics materials were manufactured by three various methods: 1) standard solid-state reaction method from Y2O3 (Sigma Aldrich, 99,9%), TiO2 (Sigma Aldrich, 99%) and SrCO3 (Sigma Aldrich,98%), 2) Pechini method, 3) wet method.

  • XPS analysis of strontium titanate ceramics

    Dane Badawcze
    open access

    The chemical composition of the strontium titanite doped with yttrium and iron ceramic samples was investigated. Samples of Y0.07Sr0.93Ti0.8Fe0.2 were prepared by solid phase reaction and sintered for 24 and 48 hours. Chemical composition was measured by UHV OmicronNanotechnology XPS system.  The analysis confirmed the chemical composition of the ceramics...

  • XPS study of the YST ceramics

    Dane Badawcze
    open access

    Yttrium-doped strontium titanate  was prepared via conventional solid-state reaction method from Y2O3 (Sigma Aldrich, 99,9%), TiO2 (Sigma Aldrich, 99%) and SrCO3 (Sigma Aldrich,98%). For comparision, two other techniques were used for synthesis: Pechini and wet methods. Both kind of samples were measured, after and before reduction process (in a hydrogen)....
