ABSTRACT In this work, the effect of microwave sintering on the properties of scandia doped zirconia (10 mol% scandia in zirconia) was investigated. The sample was prepared by mixed oxide method and the sintering was done at the temperature of 1400oC for 20 min using a 2.45 GHz microwave furnace. Sintering behavior of this microwave sintered ceramics was compared with the corresponding conventional sintered ceramics, sintered at 1400oC for 6 h in a conventional furnace. It was found that both the sintering processes produced highly dense samples. X-ray diffraction analysis confirmed the presence of only cubic structure in both the samples. Scanning electron microscopy study was done for micro-structural analysis. Further, electrical conductivity was studied from room temperature to 500oC in the frequency range of 1 kHz to 1 MHz. Higher ionic conductivity was recorded for microwave sintered sample than the corresponding conventional sintered sample. GRAPHICAL ABSTRACT

微波烧结对固体氧化物燃料电池用氧化锆基陶瓷电解质性能的影响

摘要 在这项工作中，研究了微波烧结对钪掺杂氧化锆（氧化锆中含有 10 mol% 钪）性能的影响。样品采用混合氧化物法制备，并使用 2.45 GHz 微波炉在 1400oC 的温度下烧结 20 分钟。将此微波烧结陶瓷的烧结行为与相应的常规烧结陶瓷进行比较，后者在常规炉中在 1400oC 下烧结 6 小时。发现这两种烧结过程都产生了高密度的样品。X 射线衍射分析证实两个样品中仅存在立方结构。进行了扫描电子显微镜研究以进行微观结构分析。此外，在 1 kHz 到 1 MHz 的频率范围内研究了从室温到 500oC 的电导率。微波烧结样品的离子电导率高于相应的常规烧结样品。图形概要
