“…The temperature dependence of the heat capacities of SrCeO 3 and SrZrO 3 determined by the enthalpy and scanning methods is shown in Figs. 3 and 4, together with literature data 30–35 . The experimental values for SrCeO 3 obtained in the present study well agree with the data of Cordfunke et al 30 .…”

Polycrystalline samples of strontium series perovskite‐type oxides, SrCeO3 and SrZrO3, were prepared and the thermophysical properties were measured. The chemical compositions of the samples do not deviate from the stoichiometric composition. The oxygen‐to‐metal (O/M) ratios of SrCeO3 and SrZrO3 are 3.00±0.03 and 2.98±0.01, respectively. The average linear thermal expansion coefficients are 1.11 × 10−5 K−1 for SrCeO3 and 9.69 × 10−6 K−1 for SrZrO3 in the temperature range between 300 and 1000 K. The melting temperatures Tm of SrCeO3 and SrZrO3 are 2266 and 2883 K, respectively. The longitudinal and shear sound velocities were measured by an ultrasonic pulse–echo method at room temperature in air, which enables to evaluate the elastic moduli and Debye temperature. The heat capacity was measured by using a differential scanning calorimeter in high‐purity argon atmosphere. The thermal diffusivity was measured by a laser flash method in vacuum. The thermal conductivities of SrCeO3 and SrZrO3 at room temperature are 2.95 and 4.06 W·m−1·K−1, respectively.

“…The CaO-MoO 3 phase diagram (Figure 5a) was assessed using the experimental results from Yanushkevich et al [22]. Many other thermodynamic data were used to calculate the Gibbs energy functions of CaMoO 4 [23][24][25]. The Na 2 O-MoO 3 phase diagram (Figure 5b) was assessed using phase diagram data from Caillet [26], Groshuff [27], Hoermann [28], Baloshov et al [29] and Mudher et al [30].…”

“…2. The XRD data of this perovskite phase corresponds to an orthorhombic unit cell with lattice parameters b = 857.6 (6) For the synthesis of polycrystalline SrF 2 electrolyte, well-dried SrF 2 powder was compacted into cylindrical pellets of 15 mm diameter and 3-4 mm thickness at a pressure of 300 MPa in a hydraulic press. These pellets were loaded in a zirconia boat and sintered at 1693 K for 2 h under controlled flow of the argon gas in a Pt wire wound furnace.…”

“…1. Saha et al [6] reported the enthalpy increment measurements of SrCeO 3 using a high-temperature drop calorimetry technique. Gopalan and Virkar [7] measured the thermodynamic stability of SrCeO 3 through EMF measurements by constructing galvanic cells with a molten salt electrolyte as well as CaF 2 solid electrolyte.…”
