Bu çalışmada, kobalt katkılı kalsiyum manganez oksit numunelerinin faz bileşimleri, kristal yapıları, yüzey morfolojileri ve termal özellikleri karakterize edildi. Co miktarının bu oksit yapı üzerindeki etkileri belirlendi. X-ışını kırınımı (XRD) sonuçları, kalsiyum manganez oksit fazlarının oluşumuna işaret etmektedir. Fourier dönüşümlü kızılötesi (FTIR) analizleri, her bir numune için peroksit yapısının oluşumunu doğrulamaktadır. Termal analiz sonuçları, üretilen numunelerin termal olarak kararlı olduklarını göstermektedir. Numunelerin taramalı elektron mikroskobu (SEM) gözlemleri ve enerji dağılımlı X-ışını (EDX) analizleri, Co katkısının morfolojiye etki ettiğini ve kalsiyum manganez oksit yapıya nüfuz ettiğini desteklemektedir.

Synthesis and Characterization of Cobalt-Doped Calcium Manganese Oxide Samples

Öz

In this study, the phase compositions, crystal structures, surface morphologies, and thermal properties of cobalt-doped calcium manganese oxide samples were characterized. The effects the amount of Co on this oxide structure were determined. X-ray diffraction (XRD) analysis results indicate the formation of the calcium manganese oxide phases. Fourier transform infrared (FTIR) analyses verify the formation of the perovskite structure for each sample. Thermal analysis results show that the as-produced samples are thermally stable. The scanning electron microscope (SEM) observations and energy dispersive X-ray (EDX) analyses support that the Co-doping affects the morphology and influences the calcium manganese oxide structure.
