Abstract The influence of KclO 3 addition on the AC complex susceptibility (χac) and microstructural morphology of YBCO HTSC with nominal composition Y (1−0.2x) Ba (2−0.2x) K x Cu 3 O y (x = 0 ÷ 0.40) were investigated. Xac was recorded as a function of temperature and of the concentration of KClO 3 in various AC magnetic fields up to 19 Oe. The data were analyzed using the relation h = a(1 − T m /T c ) n . The results obtained showed that the presence of K- and Cl-containing impurities on the grain boundaries change the intergranular coupling and, within certain concentration limits, improves the superconducting parameters.
