| Summary: | A study on the complex dielectric constant and the magnitude of the capacitor
impedances of the ceramic materials Calcium Copper Titanate CaCu3Ti4O12
(CCTO) and Barium Titanate (BaTiO3) with purity of 99% has been done in the
frequency range 5 kHz - 120 kHz. The measurement results showed that the
highest dielectric constant of the CCTO was found to be 745 at 5 kHz in the
sample sintered 700 0C and the highest impedance of capacitor occured in CCTO
sample non sintered that is 150434�. While the highest dielectric constant of the
BaTiO3 was 308 at 10 kHz in the sample sintered 700 0C and the highest
impedance of capacitor occur in BaTiO3 sample non sintered that was 121200 �.
The results showed that complex dielectric constant and impedance of the
capacitor of the material under study was frequency dependent. |
