Özet
Distilled water, methanol, and acetone, have been used to investigate the effects of the homogenization medium on the impedance properties of BaTiO3 ceramics produced by the solid state reaction method. The complex permittivity, complex impedance, resistivity, and complex electric modulus of the ceramics were studied by the dielectric spectrometer in a wide frequency range of 100 μHz to 20 MHz at room temperature. The complex impedance and complex electric modulus showed that the materials have a relaxation time with a different mean time constant called the Maxwell-Wagner-Sillars (MWS) type relaxation. The minimum dielectric loss found the ceramic reagents homogenized in distilled water, which is crucial for many electronic applications. The complex permittivity and resistivity measurements showed that using water instead of acetone and methanol has a positive effect on the small loss of electrical properties of barium titanate ceramics.
