Abstract
This thesis gives a quite detailed overview of piezoelectric ceramics. It will be beneficial to general reader to get basic ideas about this smart material once the reader going through this thesis. The scope of this work is limited to the development of ceramic piezoelectric, related to the scope of work which the objectives of the study are to focus on its manufacture of the green material, the poling process and the study of its physical and electrical characteristics. Processing of Barium Titanate (BaTiO3) ceramic by mixed oxide method for high technology applications involves the sequential steps; (a) powder preparation (b) powder calcining (c) de-agglomeration (d) forming (e) sintering (f) electroding (g) and poling. Each step is critical to the realization of desirable structure property relationships. To this end of the thesis, I have presented a brief introduction of the history of piezoelectric ceramics and a discussion on processing of the Barium Titanate ceramic (BaTiO3) and testing of the ceramic that define the behavior of a piezoelectric material. The ceramic was manufactured using Barium Carbonate (BaCO3) powder and Titanium Oxide (TiO2). The testing was done by using oscilloscope (waverunner) to observe the characteristic of piezoelectric ceramics. This work is organized as follows: in chapter 2 the previous work of processing a piezoelectric ceramic. Chapter 3 details the apparatus and experimental procedures used to fabricate and testing of piezoelectric ceramic. The result and discussion of the work are presented in chapter 4. To understand the behavior of a piezoelectric polycrystalline ceramics, we should know the principle of natural crystal like Quartz, Rochelle salt, and Tourmaline. Quartz crystal is naturally piezoelectric material and polycrystalline ceramic is an artificially polarized that manufactured material.
