Abstract

This study focuses on the synthesis and characterization of the Tl0.7Bi0.2Pb0.2Sr1.6Ba0.4Ca1.9Cu3O9+x (Tl-1223) superconducting phase, with particular emphasis on constructing a detailed phase diagram that maps its formation across varying temperatures and oxygen pressures. By optimizing these parameters, we were able to determine the precise conditions for obtaining a high-purity Tl-1223 phase. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to examine the crystalline structure and morphology, while magnetic properties were investigated using SQUID magnetometry. The phase diagram provides critical insights into the stability of Tl-1223, guiding future synthesis efforts. Our magnetic measurements confirmed superconducting behavior with a critical temperature of approximately 120 K, validating the optimized synthesis process. Though primarily focused on phase formation, this research also opens up the potential for applying Tl-1223 in the Future Circular Collider (FCC) as a beam screen coating material. The superconducting properties of Tl-1223 make it a promising candidate for overcoming the limitations of traditional materials under FCC operational conditions. Future work will explore the preparation of Tl-1223 films for this application.
