  • Relaxor characteristic and phase evolution of complex perovskite barium titanate bismuth zinc titanate ceramics

    Creator:
    Triamnak, Narit
    Abstract:
    Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...

  • Development of new high-temperature piezoelectric perovskite ceramics

    Creator:
    Ansell, Troy Youngmin
    Abstract:
    Lead zirconate titanate (PZT) is the dominant ferroelectric material in the market due to its excellent piezoelectric properties, relatively high Curie transition temperature (T[subscript C]), low cost, etc. However, because of emerging applications with requirements for high temperature (T[subscript C] > 400 °C) ferroelectrics, researchers are increasingly looking at alternative...

  • Understanding of Ferroelectric to Relaxor Phenomenon in Bismuth-based Perovskite

    Creator:
    Gupta, Sanu K.
    Abstract:
    It has been well established that ferroelectric to relaxor crossover in piezoelectric ceramics exhibit promising electromechanical and dielectric properties over a wide temperature range, applying sensors and actuators transducers and such. A plethora of research has reported giant strain in various lead-free piezoelectric ceramics and attributed the reasoning to the...
