Investigation of structural phase transition behavior of SrZrO3 by thermal analyses and high-temperature X-ray diffraction

In Situ Formation of Er0.4Bi1.6O3 Protective Layer at Cobaltite Cathode/Y2O3–ZrO2 Electrolyte Interface under Solid Oxide Fuel Cell Operation Conditions

“…H2 at a flow rate of 50 mL min -1 was supplied to the NiO-YSZ anode and the cathode was exposed to the ambient air. [60][61] However, in the case of LSCF-YSZ oxide couple, the reaction starts at a temperature as low as 800 o C. [62][63] This implies that the Nb The morphology of YSZ electrolyte surface in contact with directly assembled LSCFNb and ESB-LSCFNb cathodes is shown in Figure 3. The cathodes were either peeled off using adhesive tape (Figure 3b,d,f) or removed by acid treatment (Figure 3a,c,e).…”

Synthesis and in situ ion irradiation of A-site deficient zirconate perovskite ceramics

“…52,53 SrZrO 3 takes the Pbnm (a À a À c + ) structure, with temperature induced phase transitions investigated by various groups. [54][55][56] Most recently Hasegawa et al 57 revisited the SrZrO 3 system and reported transitions to Ibmm (a À a À c 0 ) at 1042 K, I4/mcm (a 0 a 0 c À ) at 1119 K and to Pm 3m (a 0 a 0 a 0 ) at 1375 K. BaZrO 3 has the aristotype perovskite structure of Pm 3m (a 0 a 0 a 0 ), with no temperature related phase-transitions reported within the literature from 10 K to 1273 K. [58][59][60] Both space groups Pcmn and Pbnm are non-stand settings of Pnma (space group 62), however, within this work we refer to the most commonly used settings within the literature.…”

Nanocrystalline SrHfO3 synthesized through a single step auto-igniting combustion technique and its characterization

“…Recently SrHfO 3 was reported as a potential material for future CMOS technology [10]. Strontium based ABO 3 perovskites such as SrZrO 3 and SrHfO 3 adopts orthorhombic structures at room temperatures, undergoes a series of structural variation and becomes cubic at elevated temperatures [11]. Cuffini et al [12] reported that SrHfO 3 is orthorhombic at room temperature, two phase transitions around 700 K (Pnma ↔ Imma) and around 1000 K (Imma ↔ Pm3m).…”
