Preparations of PZT Ceramic by Solution Combustion Synthesis
ABSTRACT
In this study, the solution combustion method was employed to synthesize perovskite PZT ceramics. Multicomponent oxides can be prepared by the solution combustion synthesis using redox exothermic reaction of precursor solutions. The results of DTA/TG showed exothermic peaks in 214$^{circ}C$ and 350$^{circ}C$. Those were caused by the differences of the thermal decomposition behavior of oxidizer and fuel. The combustion reaction was completed at 370$^{circ}C$ during heating procedure, but the product was not transformed into perovskite. The thermal decomposition behavior of both oxidizer and fuel were considered during solution combustion process at 600$^{circ}C$, which showed tetragonal single phase PZT ceramics with 50 nm crystalline size. The lattice constant a was 3.997 ${pm}$ 0.001 ${AA}$ and the lattice constant c was 4.147${pm}$0.001 ${AA}$.
Key words: PZT ceramics, Mukicomponent oxides, Solution combustion, Decomposition behaviors, Perovskite
