Abstract:

 The effects of nano-Y2O3 addition on the structural, superconducting, magnetic and mechanical properties of Bi-2223 superconducting system were investigated in this study. Bulk polycrystalline samples with general formula of Bi1.8Pb0.4Sr2Ca 2Cu3O10  δ  Y2O3 with  x; weighted  0.0-0.2-0.4-0.8-1.0 were prepared by solid state reaction method. X-ray diffraction XRD, Scanning Electron microscope SEM, Energy dispersive X-ray spectroscopy EDX mesurement, Vibrating sample mesurement VSM, Resistance- temperature ρ-T mesurement and Vickers microhardness mesurement VHM were also used for samples structural characterizations. XRD patterns showed that both Bi -2223 and Bi-2212 phases are coexist in the samples. While a lattice parameter increased, c lattice parameter decreased with increasing of nano-Y addition. In SEM photographs, it is seen that granular structure is plate-like in all samples and increase in the amount of additive, presence of point particles on the layered particles is seen more clearly. Hole concentration values that calculated from ρ-T mesurement, ranges from 0.113 to 0.160. While amount of nano-Y increased, critical transition temperatures decreased. VSM results showed that critical current density values increase with the addition of Nano-Y. VHM results showed that the hardness value increased until x 0.4 additive sample and decreased after this value.

 Bu çalışmada nano-Y2O3 ilavesinin Bi-2223 süperiletken sisteminin yapısal, süperiletken, manyetik ve mekanik özellikleri üzerindeki etkileri araştırılmıştır. Bi1.8Pb0.4Sr2Ca 2Cu3O10  δ  Y2O3 ile  x; ağırlıkça  0,0-0,2-0,4-0,8-1,0 genel formülüne sahip polikristal örnekler katıhal reaksiyon yöntemiyle hazırlandı. Örneklerin yapısal karakterizasyonları için X-ışını kırınımı XRD, Taramalı Elektron mikroskobu SEM, Enerji dağılımlı X-ışını spektroskopisi EDX ölçümü, Titreşimli numune ölçümü VSM, Direnç-sıcaklık ρ-T ölçümü ve Vickers mikrosertlik ölçümü VHM yapılmıştır. XRD desenleri, örneklerde hem Bi -2223 hem de Bi2212 fazlarının bir arada bulunduğunu gösterdi. Nano-Y ilavesinin artmasıyla a örgü parametresi artarken, c örgü parametresi azalmıştır. SEM fotoğraflarında tüm örneklerde tanecik yapısının plaka benzeri olduğu görülmekte ve katkı miktarındaki artmasıyla tabakalı yapı üzerinde nokta şeklinde partiküllerin varlığı daha net görülmektedir. ρ-T ölçümünden hesaplanan delik konsantrasyonu değerleri 0,113 ile 0,160 arasında değişmektedir. Nano-Y miktarı artarken kritik geçiş sıcaklıkları azalmıştır. VSM sonuçları Nano-Y eklenmesiyle kritik akım yoğunluğu değerlerinin arttığını göstermektedir. VHM sonuçları, sertlik değerinin x  0,4 katkılı örneğe kadar arttığını ve bu değerden sonra azaldığını göstermiştir.
