In this study, grain growth kinetics and sintering behavior
of SiO2 doped barium titanate based ceramic materials
were investigated depending on sintering temperature and
time. In this process, SiO2-doped BaTiO3 ceramic powder
substitution was prepared by solid state mixed oxide
technique. X-ray diffraction analysis showed that the main
phases formed in the sintered samples are BaTiO3. Atomic
force microscope (AFM) images were used for
examinations of the grain structure and size of the sintered
samples. Grain growth kinetic equation Gn=K.t.exp(-Q/RT)
was used for determining the activation energy of the SiO2-
doped BaTiO3 ceramic materials. It was suggested that
SiO2 is important to barium titanate ceramics not only for
sintering, but also for modifying their properties.
Keywords: Barium titanate, grain growth, kinetic, activation energy, sintering.
