| Popis: | A series of zirconium substituted barium thorates (BaTh 1-x Zr x O 3, where x = 0–0.4) were synthesized via modified solid-state reaction. The electrical conducting behavior in the oxygen and hydrogen atmospheres was investigated in the temperature range of 300–600 °C. The chemical stability towards CO 2 among these compositions was studied at 400 and 600 °C. All the Zr substituted BaThO 3 exhibited higher conductivity than pristine BaThO 3 in the oxygen atmosphere. BaTh 0.9 Zr 0.1 O 3 was found to exhibit higher conductivity in the hydrogen atmosphere with better chemical resistivity towards CO 2 at 400 °C over other compositions. |
