| Summary: | Barium titanate has major progress in research development because barium
titanate has a simple crystal structure, high constant dielectric and curie
temperature close to room temperature compare to other ferroelectric materials.
This research use barium hidroxide and titanum dioxide precursor. XRD (X-ray
difraction) result shows the second phase of barium titanate (Ba2TiO4) from the
synthesis process. Particle form of barium titanate can be observe through SEM
(scanning electron microscopy) characterization. Quantitative and qualitative
elements of barium titanate observed through EDS (energy dispersive
spectroscopy). The effect of barium titanate second phase is lowering dielectric
constant of barium titanate. Dielectric constant of barium titanate at three
sintering temperature which are 1000 C, 1100 C, and 1200 C are 148,23; 145,53;
and 207,78. |
