Abstract

In this study, crystal structure changes were investigated by dope types into cerium oxide in different ratios. The lanthanum group elements, Yb and Dy, were used as dope types. The contribution amount was 20%, and the effect of the additive and dope type on the crystal structure was evaluated. According to the findings, the total contribution rate was reduced by 10%. The hydrothermal method was used in the synthesis process. Sintering processes were carried out at 300, 600, and 900 oC temperatures and XRD were used in crystal structure determination. The particle size and element analysis were performed with SEM-EDS. As a result of the analysis studies, it was found that the total contribution rate of Ce0.9Yb0.05Dy0.05 O2with the hydrothermal method has a cubic crystal lattice. It was concluded that Ce0.9Yb0.05Dy0.05 O2compound could be used in the construction of ceramic electrolyte.

Özet

Bu çalışmada, farklı katkı türlerinin, farklı oranlarda seryum oksit içerisine katkılanması ile kristal yapı değişiklikleri incelenmiştir. Katkı türleri olarak lantan grubu elementi olan Yb ve Dy kullanılmıştır. Öncelikli olarak katkı miktarı %20 olacak şekilde katkılamalar yapılmış, katkı miktarı ve katkı türüne ait yarıçap değerlerinin kristal yapı üzerinde etkisi değerlendirilmiştir. Elde edilen bulgulara göre, toplam katkı oranı %10 düşürülmüştür. Sentez işlemlerinde hidrotermal yöntem kullanılmıştır. Sinterleme işlemleri, 300,600 ve 900 oC sıcaklıklarda gerçekleştirilerek kristal yapı aydınlatmasında ise XRD kullanılmıştır. Tanecik boyutu ve element analizi SEM-EDS ile yapılmıştır. Yapılan analiz çalışmaları neticesinde, hidrotermal yöntem ile toplam katkı oranın %10 olan Ce0.9Yb0.05Dy0.05O2 bileşiğinin kübik kristal örgüye sahip olduğu bulgulanmıştır. Seramik elektrolit yapımında Ce0.9Yb0.05Dy0.05 O2 bileşiğinin kullanılabileceği sonucuna varılmıştır.
