Article Synopsis
- The BaZrCeYO-BaPrO perovskite system is studied for its potential in high-temperature electrochemical applications, focusing on its mixed protonic-electronic conductivity and how its composition varies with Ba substoichiometry.
- Structural analysis reveals that lower Pr content and higher temperatures lead to higher symmetry phases, with the most stable phase being rhombohedral, as determined by advanced diffraction techniques.
- Conductivity results demonstrate that electron-hole transport is significant under both wet and dry conditions, with Pr enhancing conductivity in oxidizing atmospheres, while lower Pr levels improve conductivity in humidified environments due to protonic contributions.
A solid solution forms for Sr3NdNb(3-x)Ti(x)O(12-δ) with approximate limits 0 ≤ x ≤ 0.06. The system crystallizes with a 12R-type hexagonal perovskite structure in the space group R3, as determined by neutron diffraction and selected area electron diffraction.
