“…Süperiletken yapıların keşfi ve gelişimi deneysel çalışmalar üzerine temellendirilmiştir. Özellikle Cu-O tabakalı yüksek sıcaklık süperiletkenlere katkılama veya kısmi yer değiştirme yöntemleriyle birçok yeni yüksek sıcaklık süperiletken (HTS) form geliştirilmiştir [9][10][11][12][13][14]. BSCCO malzemelere molibden, vanadyum, selenyum, sodyum, potasyum, kobalt, tungsten, seryum, neodimyum, gadolinyum gibi metal, yarı metal ve ağır metal katkılamaları yapılarak birçok ara form oluşturulmuş bunların elektriksel ve manyetik özellikleri incelenerek kritik sıcaklık veya kritik akım yoğunluklarının değişimleri incelenmiştir [15,16].…”

BSCCO 2212 süperiletken sistem, ekleme ve kısmi değiştirme yöntemleri nedeniyle açık bir yapıya sahip olduğundan birçok çalışma yapılmış ve makaleler yayınlanmıştır. Bu çalışmada, BSCCO 2212 süperiletkeninde belirli bir oranda Bi-Ga kısmi yer değiştirmesi yapılarak Ga oranı artırılarak elde edilen örneklerin duyarlılığı ölçülerek Ga'nın yapının süperiletkenliğine etkisi araştırılmıştır. Her numunenin mekanik özelliklerini incelemek için Vickers mikro sertlik ölçümleri kullanıldı. Numunelerin yapısal özelliklerini belirlemek için x-ışını kırınımı (XRD) analiz sonuçları değerlendirildi ve taramalı elektron mikroskobu (SEM) görüntüleri ile kristal yapı oluşumları gözlemlendi.

“…The effect of different cationic substitutions to raise the superconducting performances, have been tested [8][9][10][11][12].Partial substitution of Bi by Pb is the most commonly used method to enhance the formation of the Bi-2223 phase [13], but after more than two decades, the formation of Bi-2223 phase remaining an open subject in the field of superconductors [14].…”

The addition of metal nanoparticles in the Bi-based superconductors has shown the disorder produced by the cations incorporation in the crystal structure affects the TC (Critical temperature) of the system. the addition of new mixture of (Cr2O3: SnO)x on high temperature superconductors HTS Bi1.6Pb0.4 Sr2Ca2Cu3O10+δ (Bi-2223) with ratio 1:1 where x = 0.0, 0.05, 0.10, 0.15 and 0.20 was investigated by solid-state reaction technique was used to prepare superconductor samples. Samples were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FS-EM), Energy Dispersive X-ray (EDX), and electrical resistivity. the results of XRD proved that the structure of 2223 remains the same even with the addition of (Cr2O3: SnO)x nanoparticles. The phase 2223 has the majority even phase Bi-2212 and phase Ca2PbO4 showed a contribution inside structure. As a result of the change physico-chemical properties resistivity of the doped optimized sample x = 0.10 was increasing 2.2 K approximately rather than the undoped one then decreased gradually up to x = 0.20. From resistivity measurement, the TC of 2223 doped with (Cr2O3: SnO)x at x = 0.10 was 113.2 K approximately. The addition of metal oxides in superconductor materials has been considered to be one of the most promising materials for large scale applications in superconducting industry.
