EFFECT OF SINTERING TEMPERATURE ON DIELECTRIC PROPERTIES OF SIO2 DOPED BATIO3 CERAMICS
Published: 10 Jul 2016
Abstract: SiO2-doped BaTiO3 ceramics were prepared by solid state mixed oxide technique. The effect of small amounts (0.3 mol %) of SiO2 additive on the microstructure, sintering behavior and dielectric properties of BaTiO3-based ceramics have been investigated. SiO2-doped BaTiO3 ceramics sintered at 1175°C, 1200°C and 1225°C for 4h in air atmosphere have been found to exhibit high density and a uniform grain size. A scanning electron microscopy, X-ray diffraction analysis and LCR meters have been used to determine the microstructure, phase analysis and dielectric properties of the SiO2 doped BaTiO3 ceramics. The SiO2 can form a liquid phase belonging to the ternary system BaO-TiO2-SiO2, leading to the formation of BaTiO3 ceramics with high density at the lower sintering temperature, and improves the sintering and dielectric properties of BaTiO3-based ceramics.
