The Effect of Milling Time and Sintering Temperature on Synthesis of PbTiO₃ by Mechanical Alloying

Abstract:

PbTiO₃ is 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, PbTiO₃ has a tetragonal perovskite structure. In this research, PbTiO₃ particles 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 TiO₂ powders. X-Ray Diffraction (XRD) and Scanning Electron Microscopy–Electron Difraction X-ray (SEM-EDX) are performed to analyze the formation of PbTiO₃ phase. It is found that the synthesized powders contain 100% PbTiO₃ phase for all sintering temperatures. The PbTiO₃ particles have agglomeration shape with a broad particle size. The electrical properties of PbTiO₃ are measured using electrical test device. Electricity test analysis shows that the synthesized PbTiO₃ behaves as semiconductor-like.
