Structural and Transport Properties of Calcium and lanthanum modified PbTiO3

A solid-state ceramic method successfully created lead titanate (PbTiO3; PT) particles. The amount of 90'domain reorientation in Calcium modified lead titanate piezoceramics, both with and without an applied field, was measured using an X-ray diffraction apparatus. Also determined is the spatial pole density distribution, which has the form [0 0 1]. In this study, we provide experimental results from our investigations into the role that parameters like calcium content, electric poling field, & microstructure play in determining the piezoelectric and electromechanical capabilities of ceramics. Particles of lead titanate (PbTiO3) were synthesized using a solid-state ceramic technique. We calcined calcium granules from 500 to 1000 degrees Celsius at a rate of 5 degrees Celsius per minute for two hours. Transmission electron microscopy and X-ray diffraction analysis confirmed the formation of well-crystalline pure phase PbTiO3 nanopowders after 900°C calcinations of the PbTiO3. PbO and TiO2 secondary phases were found when the powders were calcined at temperatures below 900 °C. Morphology and structure were evaluated using scanning electron microscopy (SEM). PLCT film shape and electric properties were investigated as a TiOx seed layer thickness. Both underwent a 600°C calcination to produce a single perovskite phase.
