Niyobyum İlavesinin (Bi, Pb)-2223 Bulk Süperiletken Sistemine Etkisi Üzerine Bir Araştırma

Niyobyum (Nb) ilaveli Bi1.85Pb0.35Sr1.9Ca2.1Cu3.1Oδ içeren bir dizi bizmut-tabanlı bulk süperiletken malzemeler, geleneksel katı hal reaksiyon yöntemi ile sentezlendi. Malzemelerin fazları ve mikro-yapısal analizi, X-ışını kırınımı (XRD) ve taramalı elektron mikroskobu (SEM) ile gerçekleştirildi. Niyobyum ilavesinin elektriksel ve manyetik özellikler üzerindeki etkisi, sırasıyla özdirenç ve mıknatıslanma ölçümleri ile belirlendi. Niyobyum ilavesiyle kritik sıcaklıkta önemli bir azalma olmadı. Ayrıca niyobyum ilave edilmiş malzemelerin oda sıcaklığı özdirenci, saf malzemeye kıyasla azaldı. Nb katkılı numunelerin kritik akım yoğunluk değerleri saf numuneninkinden daha düşüktür.

An Investigation on the Influence of Niobium Adding on (Bi,Pb)-2223 Bulk Superconducting System

A series of bismuth-based bulk superconducting materials with niobium-added Bi1.85Pb0.35Sr1.9Ca2.1Cu3.1Oδ were synthesized by the conventional solid state reaction method. The phases and microstructural analysis of the samples were carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The effect of niobium addition on electrical and magnetic properties was determined by resistivity and magnetization measurements, respectively. There was no significant reduction in critical temperature by the addition of niobium. Also the room temperature resistivity of the niobium added samples decreased compared to the pristine sample. The critical current density values of the samples with Nb addition were lower than the pure sample.
