Özet

Bu çalışmada, Bi1.7Pb0.3Sr2-x(Eu)xCa2Cu2.75Na0.25Oy (x = 0.00, 0.20, 0.25 ve 0.30) süperiletken sisteminin morfolojik yapısı ve mekanik özellikleri incelenmiştir. Katı hal tepkime yöntemi ile hazırlanan nano boyutlu Eu (80 nm) katkılı seramik örneklerin faz oluşumu, morfolojik yapısı ve mekanik özellikleri sırasıyla X-ışını kırınımı (XRD), taramalı elektron mikroskobu (SEM) ve Vickers mikrosertlik cihazı ile karakterize edilmiştir. X-ışını ölçüm verilerinde Bi, Pb-2223 yüksek sıcaklık fazları, Bi-2212 düşük sıcaklık süperiletken fazı ve minör safsızlık fazı üretimi tespit edildi. Tetragonal simetriye sahip Bi-2223 süperiletken fazı, tüm numunelerde temel faz yapısıdır. SEM inceleme bulgularına göre, plaka benzeri tane tiplerinde Bi-2223 fazı tespit edilmiştir. Taneciklerin düzgün dağılımı ve aralarında güçlü bağlantılar ile x = 0,25 nano boyutlu oranda Eu içeren örnek daha az gözenekli bir morfolojik yapıya sahiptir. Güçlü tanecikler arası bağlar ve az boşluklu yapı oluştuğu için, x = 0,25'te nano boyutlu Eu katkısı olan örnek, mikro sertlik ölçümünün sonuçlarına göre en iyi mekanik özellikleri sergilemiştir.

Abstract

In this paper, the morphological, structure and mechanical properties of the superconducting system Bi1.7Pb0.3Sr2-x(Eu)xCa2Cu2.75Na0.25Oy (x = 0.00, 0.20, 0.25 and 0.30) have been investigated. Phase formation, morphological structure and mechanical properties of nano-sized Eu (80 nm) substituted ceramic samples prepared by solid state reaction method were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Vickers microhardness instrument, respectively. Bi, Pb-2223 high temperature phases, Bi-2212 low temperature superconductor phase, and minor impurity phase production were identified in the X-ray measurement data. In all samples, the main phase structure is the tetragonal symmetric Bi-2223 superconducting phase. According to the SEM examination findings, the Bi-2223 phase has been detected by flaky plate-like grain types. With a uniform distribution of grains and strong connections between them, the sample containing Eu at the nano-sized ratio of x = 0.25 has a less porous morphological structure. Because strong intergranular bonds and a decreased void structure were formed, the sample with nano-sized Eu substitution at x = 0.25 exhibited the best mechanical properties, according to the results of the microhardness measurement.
