Abstract: High permittivity barium titanate zirconate (BTZ) is often used for dielectrics in commercial multilayer ceramic capacitors, actuators applications, and is a highly promising material for dynamic random access memory (DRAM) and microelectromechanical system (MEMS) applications due to its very stable, high insulating characteristic against voltage. Especially, the material is promising for environmental friendly application in compared to Lead (Pb) based compositions. Different solid solutions in the system have been synthesized via solid state reaction route. Detailed phase formation behaviors of the solid solutions were investigated through; (i) phase identification, (ii) phase quantity determination, (iii) change in lattice parameters and crystallite sises, (iv) evolution of phase formation kinetics and reaction mechanism, and (v) structure and microstructure evolution by Rietveld refinement method. The study on reaction mechanism concludes that; titanates form more easily...
