Abstract

The influence of KClO₃ addition on the AC complex susceptibility and parameters of microstructure and morphology of YBCO HTSC with nominal compositions Y₁Ba_(2-X)K_xCu₃O_y, Y_(1-0.2x)Ba_(2-o.2x)K_xCu₃O _y and Y₁Ba₂CU_(3.5-x)K_xO_y, (x = 0-0.75) were investigated. Experimental results showed a promoting effect of the addition on the formation of 123-phase in air. The superconducting transition temperature for all KClO₃-doped samples was found to be higher (T_c,conset ∼ 94 K) than that for undoped YBCO. The comparison of the properties of YBCKO demonstrated that the additive had a specific effect on the magnetic susceptibility and microstructure of samples with different nominal compositions.
