The Effect of Milling Time and Sintering Temperature on Synthesis of PbTiO3 by Mechanical Alloying
PbTiO3is one of electroceramic materials which can be applied for electronics and microelectronics due to their dielectric, pyroelectric, and piezoelectric properties. The members of PbTiO3-based ferroelectrics are widely used in multilayer, actuator and sensor capacitor. At room temperature, PbTiO3has a tetragonal perovskite structure. In this research, PbTiO3particles are synthesized by mechanical alloying method with variation of milling time and sintering temperature. The milling time variation is taken for 10, 20 and 30 hours. Sintering temperature variation is performed at 850, 900 and 1000°C. The powders used in the milling process are PbO and TiO2powders. X-Ray Diffraction (XRD) and Scanning Electron Microscopy–Electron Difraction X-ray (SEM-EDX) are performed to analyze the formation of PbTiO3phase. It is found that the synthesized powders contain 100% PbTiO3phase for all sintering temperatures. The PbTiO3particles have agglomeration shape with a broad particle size. The electrical properties of PbTiO3are measured using electrical test device. Electricity test analysis shows that the synthesized PbTiO3behaves as semiconductor-like.
