| Abstract | In this work, nano-SnO$_{2}$ (<100 nm) added samples in Bi$_{1.7−x}$Pb$_{0.3}$Sn$_{x}$Sr$_{2}$Ca$_{2}$Cu$_{3}$O$_{y}$ (x = 0.00–0.20) were prepared by conventional solid-state reaction method. The phase formation, volume fraction and lattice parameters were characterized using X-ray powder diffraction measurements. Surface morphology and grain connectivity of the samples were identified by using scanning electron microscope (SEM). Diamagnetic onset temperatures (T c on ) and hole concentration (p) of SnO$_{2}$ added samples were determined by ac susceptibiliy measurements. AC susceptibility measurements showed that diamagnetic onset temperatures (T c on ) of samples Sn0 (x = 0.00), Sn1 (x = 0.05), Sn2 (x = 0.10), Sn3 (x = 0.15) and Sn4 (x = 0.20) are 108.559, 109.985, 101.281, 101.670 and 92.676 K, respectively. SEM measurements showed that not only the surface morphology and grain connectivity degrade but also the grain size of the samples decrease with the increase of the Sn addition. Also, addition of SnO$_{2}$ nanoparticles increases the impurities, voids and porosity. X-ray diffraction patterns of all samples indicated the majority of Bi-2223 and Bi-2212 phases along with minor impurity phase Ca$_{2}$PbO$_{4}$. The volume fraction of the Bi-2223 phase for the sample with x = 0.10 SnO$_{2}$ showed the highest percentage (49.49) and with further increasing SnO$_{2}$, the volume fraction of the Bi-2223 phase decreases and Bi-2212 phase increases. All SnO$_{2}$ nanoparticles added samples showed quite similar lattice parameters compared with non-added sample. These results indicate that nano SnO$_{2}$ does not have significant impact on the lattice parameters. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
