“…In order to overcome this problem, numerous works have been completed and from their results, great progress has been achieved towards the enhancement of the transport properties of this high T c superconductor phase [1,4,6,12]. There are several reports studying the effect of various factors on the transport properties of Bi-2223 phase [1,6,[13][14][15][16][17], like using different methods (sol-gel, spark plasma, solid state) [10,18,19], preparation conditions (calcination procedure, sintering temperature, time, pressing load [20] and so on), precursor powder size, adding nanoparticles to the main material [21], and the partial substitution of elements in the BSCCO system [1,2,12,15,20,[22][23][24][25][26][27][28][29][30]. The studies have shown that the sintering and calcination temperature is the predominant factor for the formation of the BSCCO 2223 phase compared to the sintering time [2,4,6].…”

“…Li et al investigated the effect of the fabrication process, such as using different chelating agents and process parameters. They reported that the sample obtained using glucose acid (GA) as the chelating agent, had better electrochemical performance [16]. Also, it was reported that the preparation process of the GA sample was shorter than the other samples such as ethylenediamine tetraacetic acid (EDTA) [16].…”

“…Here, we show that for the formation of the desired gel for fabrication of a BSCCO system less than 24 h is needed. In [16] this preparation time required up to two weeks.…”

The influence of using two different starting materials (nitrates and carbonates) and calcination processes on the grain boundary properties of a BSCCO system have been investigated. Superconducting BSCCO samples with the chemical composition Bi1.64Pb0.34Sr2Ca2Cu3Oy were successfully fabricated by the sol–gel method. X-ray diffraction (XRD) and scanning electron microscopy analyses have been used to study the phase formation and microstructure of the prepared samples, respectively. The DC electrical resistivity, critical current density, and AC susceptibility of the samples were measured. The XRD result showed that one can improve the phase formation of the Bi-2223 system by choosing suitable starting materials and the temperature of calcination. AC susceptibility and DC electrical resistivity revealed that the synthesis process improves the grain boundaries. The critical current density (measured in 77 K) increased from 100 A cm−2 to about 145 A cm−2. In fact, the critical current of the sample fabricated with a carbonates group and calcinated at 750 °C obtained 100 A cm−2, while a sample that was fabricated with a nitrates group and calcinated at 790 °C had the critical current of 145 A cm−2.

“…It is generally believed that the Bi-2223 phase is formed through the reactions between Bi-2212 phase and some Cu/Ca-rich phases. As a result, Bi-2212 phase is inevitably present in Bi-2223 thin films, making it difficult to fabricate them [23][24][25]. In addition, the Bi-2223 lead with a high phase-forming temperature and a low melting point is often added to form some liquid phases so as to lower the reaction temperature and promote the reaction [26][27][28].…”

In this work, a (Bi, Pb)2Sr2Ca2Cu3O10+δ ((Bi, Pb)-2223) solution with good film-forming capability and chemical stability was synthesized through using metal acetates as raw materials, acrylic acid as an additive, and anhydrous methanol as a solvent to adjust the sol formula. Subsequently, (Bi, Pb)-2223 thin films were fabricated on LaAlO3 (LAO) single-crystal substrates via dip-coating technology at different heat treatment temperatures, and the structures and properties of (Bi, Pb)-2223 films were characterized. It was found that when the sol stoichiometric ratio of Bi : Pb : Sr : Ca : Cu was controlled at 1.9 : 0.35 : 2 : 2 : 3 and the gel film was heat-treated at 860℃ and dwelled for 120 minutes in an mixed atmosphere of N2 : O2 = 96 : 4, the prepared thin film with a pure (Bi, Pb)-2223 superconducting phase exhibited excellent biaxial texture, a dense surface structure, and had a Tc of 106 K and a ΔTc of 6 K. The microstructure analysis revealed a layered epitaxial growth of the film along the LAO substrate with a regular arrangement of atoms and a consistent interlayer spacing.

“…Since the discovery of BSCCO [9], chemical doping, which can be in the form of addition or substitution, has become one of the most used methods to enhance Tc and critical current density (Jc) or to uncover its physical and magnetic properties [10][11][12][13][14][15][16]. In addition to chemical doping, many synthesis routes are available to produce BSCCO bulk materials including solid state reaction [17], co-precipitation [18], sol-gel [19], and polymer matrix method [20]. Among these aforementioned methods, solid state one is frequently used by researchers owing to its advantages such as simplicity, cheapness, and reasonable reproducibility [14].…”

Bu çalışma, sırasıyla x = 0, 0.5, 1 ve 2 için %x ağırlıkça Co3O4 nano parçacıklarıyla eklenmiş Bi-2212 seramiğindeki kristal kalitesi, faz bileşimleri, süperiletken özellikler ve çivileme kuvvetindeki dikkate değer değişimlerle ilgilidir. XRD analizi, Co3O4-içeriği XRD piklerinde genişlemeye, kristal kalitesinin düşmesine ve Bi-2212 miktarının azalmasına yol açtığı sonucuna varır. SEM'den Co3O4 ilavesiyle çubuksu yapıdan plakamsı yapıya doğru bir evrilme olduğu görülmektedir. Kritik geçiş sıcaklığı (Tc), M-T ölçümlerinden saf örnekte 82 K olarak bulunmuş ve 0.5% Co örneğinde 65 K’ye 1% Co örneğinde 42 K’ye kademeli olarak düştükten sonra süperiletkenlik 2% Co örneğinde kaybolmuştur. M-H ölçümlerinden, histerezis eğrilerinin Co3O4 eklenmesi ve sıcaklıkla birlikte daraldığı görülmektedir. Buna bağlı olarak, kritik akım yoğunlukları (Jc) ve çivileme kuvvetleri (Fp), Co3O4 içeriğindeki artışın neden olduğu süper iletken tanecikler arasındaki bağlantıdaki bozulmalar nedeniyle azalmıştır.
