dc.description.abstractThis thesis presents three studies in the synthesis and characterization of three ferroelectric solid solutions that were hypothesized to be viable replacements for the lead-based industry standard material Pb(Zr,Ti)O3 (PZT), due to both environmental concerns and physical property limitations. The first chapter is an introduction to ferro and piezoelectricity along with the perovskite structure. It also describes how element selection and structural deviation can be utilized to design novel materials with targeted properties. The first research chapter involves the (1-x) Na0.5Bi0.5TiO3 – (x)BaTiO3 (NBT-BT) system doping in group 13 elements onto the B-site in order to improve the ferroelectric properties. The third chapter explores the idea of using a polarization extension to form a Morphotropic Phase Boundary (MPB) between paraelectric and ferroelectric phases through compositional changes. The solid solution (1-x) NaNbO3 – (x)BaZrO3 (NN-BZ) was synthesized, and the electromechanical properties were measured in order to see if there was in increase in the piezoelectric response. Chapter four describes the synthesis of a ferroelectric solid solution that improves on PZT’s Curie temperature. Due to this research, a new solid solution (1-x)Bi(Fe2/8Ti3/8Mg3/8)O3 – (x)PbTiO3 (BFTM-PT) was synthesized, and the electromechanical properties were measured.
