Investigation on the Effects of Zn on PbTiO3
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℃ and sintered at 1,100 ℃ 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.
