In this paper, Bi1.66Pb0.34Sr2Ca2Cu3O superconductor powders have been prepared via sol-gel and solid-state reaction methods. The structural and magnetic properties have been studied by the X-Ray diffraction (Fullprof analysis) and magnetic susceptibility measurements. The superconductivity and structural properties of the samples have been compared with the properties of a commercially availab...
CaCO3 nanoparticles have been synthesized via heat-treatment of a new precursor and solid state reaction. Effect of calcinations temperature and quantity of surfactant on particle size has been investigated. The products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier transform infrared (FT–IR) spec...
