Bi(1,8- x)Pb0,2GaxSr2CaCu2Oy Süperiletken Yapıda Bi-Ga Kısmi Değişiminin Manyetik, Mekanik ve Mikroyapısal Özellikleri Üzerindeki Etkisinin İncelenmesi

BSCCO 2212 süperiletken sistemi, ekleme ve kısmi değiştirme yöntemlerine açık bir yapıya sahip olduğundan, birçok çalışma yapılmış ve makaleler yayınlanmıştır. Bu çalışmada, BSCCO 2212 süperiletkeninde belirli bir oranda Bi-Ga kısmi yer değişimi yapılarak Ga oranının arttırılması ile elde edilen numuneler üzerindeki duyarlılığın ölçülmesi ile Ga'nın süperiletken yapı üzerindeki etkisi araştırılmıştır. Her numunenin mekanik özelliklerini incelemek için Vickers mikro sertlik ölçümleri kullanılmıştır. Örneklerin yapısal özelliklerini belirlemek amacıyla x-ışını kırınım (XRD) analiz sonuçları değerlendirilmiş ve taramalı elektron mikroskobu (SEM) görüntüleri ile kristal yapı oluşumları gözlenmiştir.

The Investigation of Bi-Ga Partial Replacement Effect on Magnetic, Mechanical and Microstructural Properties of Bi(1,8- x)Pb0,2GaxSr2CaCu2Oy Superconductor

Since the BSCCO 2212 superconducting system has an open structure due to the addition and partial replacement methods, many studies have been carried out and the articles have been published. In this study, the effect of Ga on the superconductivity of the structure was investigated by measuring the susceptibility on the samples obtained by increasing the Ga ratio by performing Bi-Ga partial replacement at a certain ratio in the BSCCO 2212 superconductor. Vickers micro hardness measurements were used to examine the mechanical properties of each sample. x-ray diffraction (XRD) analysis results were evaluated in order to determine the structural properties of the samples and crystal structure formations were observed by scanning electron microscope (SEM) images.
