| Abstract | Ferroelectric Glass-ceramics of the Na$_{2}$O–BaO–Nb$_{2}$O$_{5}$–SiO$_{2}$ system were obtained from controlled crystallization process performed on the parent glass of composition (24-x)Na$_{2}$O-xBaO-26Nb$_{2}$O$_{5}$-50SiO$_{2}$ where x = 4 was selected. Nd$_{2}$O$_{3}$ doping was applied in the range 0–3 mol%. X-ray diffraction analysis indicated that NaNbO$_{3}$ and NaBa$_{2}$Nb$_{5}$O$_{15}$ crystals formed as two main crystalline phases. Their relative intensities varied with treatment temperature. Crystalline sizes of both NaNbO$_{3}$ and NaBa$_{2}$Nb$_{5}$O$_{15}$ calculated from XRD peak broadening were in nanoscale range. Increasing of doping content also gave a parent glass with higher bulk density. The dielectric constant measured at room temperature for glass-ceramic samples was found to be sensitive to the presence of NaBa$_{2}$Nb$_{5}$O$_{15}$ phase. The results of the present work suggest that introduction of Nd$^{3+}$ into Na$_{2}$O-BaO-Nb$_{2}$O$_{5}$-SiO$_{2}$ system not only alters the dielectric response but also changes the phase transition behaviors of the co-existant ferroelectric phases by suppressing the growth of the NaBa$_{2}$Nb$_{5}$O$_{15}$ crystals. |

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.
