| Abstract |
Synthesis of Zn-doped PbTiO3 was done using solid-state method. The effects of varying
amount of Zn were investigated. Stoichiometric amount of precursors were mixed and ground. The
pressed mixtures were calcined at 800°C and sintered at 1,100 °C after regrinding. The samples were
characterized using X-ray Diffraction (XRD), Differential Thermal Analysis (DTA), and Scanning
Electron Microscopy (SEM). The XRD verifies the existence of PTO in the samples. DTA shows the
thermal profile of the samples. Among the different concentrations of Zn that were added, the sample
with 5% mole fraction showed the lowest melting point. For 5% mole fraction and greater, SEM
images showed flattening and fusing of grains. |
