Effect of doping method on microstructural and defect profile of Sb-BaTiO3

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 surfa...
