In this study the influence of nano-SnO2 particles addition on the critical current density (JC) in Bi1.6Pb0.4Sr2Ca2Cu3SnxO10 superconductor ceramic with x ranging from 0 to 0.05 was investigated. The samples were prepared using the co-precipitation technique with sintering time of 48 h at 850ºC. The characterizations were carried out using DC resistivity measurement, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The critical current density, JC and the transition temperature, Tc-onset for sample with 0.02 wt% were found to be the highest with a maximum JC 1212 mA/cm2 and a maximum TC-onset 112 K.  XRD and SEM analysis indicated that nano-SnO up to 0.02% wt  enhance the formation of low-TC (Bi-2212) phase fraction.
