Improved electrical properties of SiO 2 -added BaTiO 3 ceramics by microwave sintering
Source abstract
Abstract
Abstract SiO2 added BaTiO3 ceramics were successfully prepared by microwave sintering at low temperatures. Pure BT ceramic showed very high dielectric constant (11022) at Curie point. When SiO2 was 0.5 wt%, no second phase was detected and it showed homogeneous microstructure with small grains; however, with further increase of SiO2 addition to 1 and 2 wt%, Ba2TiSi2O8 was detected and columnar grains appeared. The improvement of densification and appearance of second phase were all effective to improve the electrical breakdown strengths and reached 46 kV/cm.
