Researchers developed textured bismuth layer-structured piezoelectric ceramics (Na0.5Bi4.5Ti4O15) for high-temperature applications. This novel texturing method significantly enhances piezoelectric properties while maintaining high Curie temperatures.

Area of Science:

  • Materials Science
  • Ceramic Engineering
  • Solid State Physics

Background:

  • Bismuth layer-structured piezoelectric ceramics, specifically Na0.5Bi4.5Ti4O15 (NBT), are promising for high-temperature applications due to high Curie temperatures (Tc).
  • Limited piezoelectric performance in NBT ceramics is attributed to crystal structure constraints on spontaneous polarization, hindering widespread application.

Purpose of the Study:

  • To develop a fabrication route for textured NBT ceramics with enhanced piezoelectric properties.
  • To investigate the effect of template-induced grain alignment on piezoelectric performance and electrical properties.

Main Methods:

  • Fabrication of (00l)-textured NBT ceramics by mixing plate-like templates with solid-state-derived matrix powder.
  • Conventional sintering to induce grain alignment via templates.

  • Characterization of structural, piezoelectric, dielectric, and electrical properties.

    • Main Results:

    • Achieved (00l)-textured NBT ceramics with a high Lotgering factor of 80.6%.
    • Exhibited an ultrahigh piezoelectric coefficient (d33) of 41.1 pC/N, a low dielectric loss (tan δ = 0.48%), and a high Curie temperature (Tc) of 660 °C.
    • Template-induced grain alignment was confirmed to facilitate domain switching and enhance piezoelectric properties without significantly degrading electrical resistivity.

    Conclusions:

    • A simple and effective method for fabricating textured NBT piezoelectric ceramics was demonstrated.
    • Template-induced texturing significantly improves piezoelectric performance for high-temperature applications.
    • This approach provides valuable insights for designing high-performance textured bismuth layer-structured piezoelectric materials.
