Abstract

Microstructures and microwave dielectric properties of Alkali cation displacement of 0.4ATiO 3 -0.6La(Mg 0.5 Ti 0.5 )O 3 (A = Ca,Sr,Ba) ceramics were investigated. With the alkali cation displacement, namely the increase of the A-site cation radii, the bulk density increased with the rise of sintering temperature obviously while the higher temperature caused the decrease of bulk density. As the increase of radii, diffraction peaks shifted to low angle by XRD which illuminated the volume of unit cell reduced. The 0.4ATiO 3 -0.6La(Mg 0.5 Ti 0.5 )O 3 (A = Ca, Sr, Ba) ceramics showed a dense microstructure without the presence of second phases by XRD and SEM. The relationship of properties and tolerance factor were discussed.
