We report the effect of Zn Substitution on superconducting and normal state properties of new Y-based Y3Ba5Cu8-x Zn (x) O18-delta superconductor. The resistivity of the samples rather shows linear temperature dependence. Two cases of bipolaron model, in presence and absence of thermally excited individual polarons, are used to analyze normal state resistivity. The effect of Zn substitution on carrier localization, transition temperature, boson-boson relaxation time, and extended bosons are discussed.
