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)KxCu3Oy, Y(1-0.2x)Ba(2-o.2x)KxCu3O y and Y1Ba2CU(3.5-x)KxOy, (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 (Tc,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.
