Resumen:
Electrical properties in BaTiO3 based ceramics are strongly dependent on composition and microstructural development. In this work, we studied the effect of the particle coating as doping method on microstructure and electrical properties of Sb-doped BaTiO3. The advanced doping method involved surface-coated BaTiO3 particles with a thin film of a metal-organic precursor solution. Results were compared with the performance obtained on conventional doping method. The particle coating as doping method led to an effective grain growth inhibition as well as significant microstructure improvement.
