Effect of MgO addition on the microstructure and dielectric properties of BaTiO3 ceramics
Source abstract
Abstract
Abstract MgO-doped BaTiO 3 (BaTiO 3 /MgO) ceramics were prepared by a solid-state sintering method. The effects of MgO doping on the dielectric properties of BaTiO 3 /MgO were investigated in terms of its microstructural development. The BaTiO 3 /MgO was characterized by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and x-ray powder diffraction. Results show that grain growth of the BaTiO 3 /MgO during sintering was inhibited by adding MgO at least 0.5 mol%. It resulted in a high resistance of the BaTiO 3 /MgO sintered at high temperature. The BaTiO 3 /MgO possessed a broad temperature stability and met Electronic Industries Association (EIA) ×7R specification. The improved dielectric properties of the BaTiO 3 /MgO are attributed to the decreased tetragonality of BaTiO 3 lattice due to Mg 2+ substitute for Ti 4+ .
