Alkaline earth–doped $ La_{2} %$ Zr_{2} %$ O_{7} $ oxides with a pyrochlore structure: phase equilibria and electrical properties
Abstract A row of $ La_{2 − x} %$ Sr_{x} %$ Zr_{2} %$ O_{7 − δ} $ (x = 0.00, 0.05, 0.10, 0.15, 0.50) oxides was synthesized using the citrate–nitrate method. The solubility limit for strontium in $ La_{2} %$ Zr_{2} %$ O_{7} $ was found to be 0.07 according to the XRD analysis. At a higher strontium...

| 520 | |a Abstract A row of $ La_{2 − x} %$ Sr_{x} %$ Zr_{2} %$ O_{7 − δ} $ (x = 0.00, 0.05, 0.10, 0.15, 0.50) oxides was synthesized using the citrate–nitrate method. The solubility limit for strontium in $ La_{2} %$ Zr_{2} %$ O_{7} $ was found to be 0.07 according to the XRD analysis. At a higher strontium content, the second phase of $ SrZrO_{3} $ was observed. Electrical conductivity of $ La_{0.95} %$ M_{0.05} %$ Zr_{2} %$ O_{7 − δ} $ (M = Ca, Sr) oxides has been studied by means of impedance spectroscopy in wet and dry air in the temperature range of 300–550 °C. Total electrolyte resistance was divided into bulk and grain boundary contributions. The total, bulk, and grain boundary conductivity values in wet air were found to be higher than the corresponding values in dry air. The response of the Sr-doped oxide on humidifying the atmosphere was found to be more pronounced than that of the Ca-doped one. The influence of acceptor doping on electrolyte conductivity is discussed. | ||

Electrical conductivity of $ La_{0.95} %$ M_{0.05} %$ Zr_{2} %$ O_{7 − δ} $ (M = Ca, Sr) oxides has been studied by means of impedance spectroscopy in wet and dry air in the temperature range of 300–550 °C. Total electrolyte resistance was divided into bulk and grain boundary contributions. The total, bulk, and grain boundary conductivity values in wet air were found to be higher than the corresponding values in dry air. The response of the Sr-doped oxide on humidifying the atmosphere was found to be more pronounced than that of the Ca-doped one.

The solubility limit for strontium in $ La_{2} %$ Zr_{2} %$ O_{7} $ was found to be 0.07 according to the XRD analysis. At a higher strontium content, the second phase of $ SrZrO_{3} $ was observed. Electrical conductivity of $ La_{0.95} %$ M_{0.05} %$ Zr_{2} %$ O_{7 − δ} $ (M = Ca, Sr) oxides has been studied by means of impedance spectroscopy in wet and dry air in the temperature range of 300–550 °C. Total electrolyte resistance was divided into bulk and grain boundary contributions. The total, bulk, and grain boundary conductivity values in wet air were found to be higher than the corresponding values in dry air. The response of the Sr-doped oxide on humidifying the atmosphere was found to be more pronounced than that of the Ca-doped one. The influence of acceptor doping on electrolyte conductivity is discussed.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Lanthanum zirconate</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pyrochlore</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Proton conductivity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bulk</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Grain boundary</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tropin, Evgeniy</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Khodimchuk, Anna</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Ionics</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">28(2022), 11 vom: 15.

Alkaline earth–doped $ La_{2} %$ Zr_{2} %$ O_{7} $ oxides with a pyrochlore structure: phase equilibria and electrical properties |
| abstract |
Abstract A row of $ La_{2 − x} %$ Sr_{x} %$ Zr_{2} %$ O_{7 − δ} $ (x = 0.00, 0.05, 0.10, 0.15, 0.50) oxides was synthesized using the citrate–nitrate method. The solubility limit for strontium in $ La_{2} %$ Zr_{2} %$ O_{7} $ was found to be 0.07 according to the XRD analysis. At a higher strontium content, the second phase of $ SrZrO_{3} $ was observed. Electrical conductivity of $ La_{0.95} %$ M_{0.05} %$ Zr_{2} %$ O_{7 − δ} $ (M = Ca, Sr) oxides has been studied by means of impedance spectroscopy in wet and dry air in the temperature range of 300–550 °C. Total electrolyte resistance was divided into bulk and grain boundary contributions. The total, bulk, and grain boundary conductivity values in wet air were found to be higher than the corresponding values in dry air. The response of the Sr-doped oxide on humidifying the atmosphere was found to be more pronounced than that of the Ca-doped one. The influence of acceptor doping on electrolyte conductivity is discussed. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2022.
