Effect of sintering temperature on phase formation, microstructure and dielectric properties of nanogold modified barium titanate ceramics
In this work, BaTiO3ceramics modified with 0.5 mol% Au nanoparticles were fabricated by using a combination of the solid-state reaction and pressureless-sintering techniques. By employing a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), Arc...
