Based on the analysis of the studied properties, the paper presents the developed technology for the manufacture of high-temperature superconducting (HTSC) ceramics based on ultrafine powders; in this case, the method of dry pressing under the influence of an ultrasonic signal is considered. Based on the analysis, the optimal technology variants for synthesizing HTSC ceramics were selected. Data are presented on the performance properties of HTSC ceramics, samples of electromagnetic field screens, volumetric microwave resonators, and ceramic squids. Also, a method of positron annihilation is described, measuring the lifetime of positrons and measuring the curves of the angular distribution of annihilation photons (ADRP), which makes it possible to identify defects of the vacancy type (vacancies, clusters of vacancies, loops, dislocations).
