“…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.

“…A summary of the thermodynamic properties of the four compounds is given in Table . The calculated values are not only in good agreement with our new experimental data but also reproduce most of the literature data, except the entropies of formation from oxides at 298 K assumed by Dash et al Banerjee et al determined the heat capacity of Sr 4 Zr 3 O 10 and Sr 3 Zr 2 O 7 by differentiation of analytical expressions fitted to relative enthalpy measurements, which are about 8% higher than those measured in the present work as well as those calculated by NKR. The original data and the measured relative enthalpies are marked in Figure to compare with H T ‐H 298 calculated using the present parameters.…”

Thermochemistry of the ZrO₂–SrO System: From enthalpies of formation and heat capacities of the compounds to the phase diagram

et al. 2019

The thermodynamics of the ZrO2–SrO system is of interest for the optimization of synthesis and applications of functional materials and high‐temperature structural ceramics. Earlier data on phase relationships and thermodynamic properties of the system are unfortunately scattered and inconsistent. In this study, the compounds Srn+1ZrnO3n+1 (n = 3, 2, and 1) were prepared by solid‐state reaction. Their heat capacities from 573 to 1273 K were measured by differential scanning calorimetry and their enthalpies of formation from component oxides at 298 K were determined by high‐temperature oxide melt solution calorimetry. The CALPHAD method was used to assess the ZrO2–SrO system, using both available literature data and our new measurements. A self‐consistent thermodynamic database and the calculated phase diagram of the ZrO2–SrO system are provided. This work is a prerequisite for accurate predictions of the relationships among the composition, temperature, and microstructure of complex functional and structural materials containing ZrO2 and SrO.

“…Blasse et al [3] have reported the uncommon yellow emission at 540 nm for Ca 3 ZrSi 2 O 9 . The bulk material properties and structures of SrZrO 3 are well known [2,[4][5][6]. However, it is now widely accepted that materials exhibit novel properties when their sizes decreased to nanometer scales, and the performance of materials depends largely on the synthesis procedure.…”
