This paper represents an attempt in the obtaining of metal-ceramic composite precursor powders in the Ag:Bi-based superconductor system with uniform distribution of comprised phases through spray pyrolysis method. The process involves aerosol formation ultrasonically (800 kHz) from the urea-modified nitrates precursor solution (for the fixed cation ratio Bi:Pb:Sr:Ca:Cu=1.8:0.2:2:2:3 and for the Ag fraction of 20 wt.%) and control over the aerosol decomposition united with self-combustion of droplets in a high-temperature tubular flow reactor in the temperature range up to 820 o C. Following the initial attempts in providing of the 2223 phase high contents, particles were additionally calcined for 2 h in air and oxygen, at 825 and 810 o C respectively. Structure, morphology and compositional stoichiometry of synthesized powders were followed in accordance to various analysis methods (XRD, DTA, SEM and EDS).
