Lead Zirconate Titanate (PZT), a very important perovskite material, has been fabricated by ceramic processing method. Dependence of dielectric properties on temperature and frequency of electric field has been investigated. A two layered RC circuit model resembling grain and grain-boundary is employed to analyze the variation of dielectric constant with frequency of electric field. Fluctuations in the measure of dielectric constant are indicative of the presence of defects and impurities in the grain boundary region. Temperature effect has been described by the structural change caused by phase transition which is quite susceptible to the ratio of Zr to Ti in material composition. Specifically near morphotropic phase boundary (MPB) with the presence of mixed tetragonal and rhombohedral phases, a large variation of dielectric constant can effectively be explained by Maxwell-Wagner relaxation of polarization charges at the grain-grain boundary interface.Keywords

There is sufficient reason to continue the publication of REASON which took its birth at a critical juncture of our college, when the college was gaining its multidimensional progress at rapid pace by essentially knocking and unveiling the secret of fiourishment and identification. It is only untiring effort for sincere dedication which has been elevating the taste and growth of REASON. Students, teachers, staff members of our college are all keen enough to publish the super quality magazine REASON enriched with technical matters which have occurred are likely to occur at various corners of the world in emergent areas of technology.- From the Principal's Desk

It gives me immense pleasure to know that the family members of this Kalyani Government Engineering College is publishing the seventh issue of the technical journal of this college. The publication of this magazine, which is essentially a technical one, reveals once again that the students of this college are confined not only to their regular studies for the examinations, but in addition they roam about various corners of knowledge to quench their thirst of curiosity in all respects.- Electro Medical Therapy
