Özet

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.
