The influence of KClO3 addition on the magnetic properties and microstructure of YBCO HTSC materials with nominal composition (A): Y1Ba2-xKxCu3Oy, (B): Y1-0.2xBa2-0.2xKxCu3 Oy, (C): Y1Ba2Cu3.5-xKxOy (x = 0-0.75) were investigated. Magneto-optic imaging of flux distributions was employed to study the grain connectivity in the doped and undoped samples in a direct way. The obtained flux patterns taken at various temperatures reveal that KClO3-doped samples (x = 0.30) exhibit flux distributions being close to those being observed in melt-textured superconductors. This demonstrates that the grain connectivity in the doped samples is considerably improved as compared to pure ones, which is an important issue for the fabrication of coated conductors of YBCO.
