Composition and Dielectric Properties of Ba2Ti9O20-BaFe12O19 Ceramics


Article Preview

In this paper, the composition and dielectric properties of Ba2Ti9O20-BaFe12O19 system ceramics were studied. The ceramics were prepared successfully through the conventional ceramic processing. The x-ray diffraction results showed that all specimens were made of multi-phases, and the sintering temperature on the phase structure of the ceramics did not affected. The effects of sintering conditions and the components on the dielectric properties were investigated in detail. The investigations indicated that the initial Ba2Ti9O20/ BaFe12O19 ratio had a great effect on the dielectric of the ceramics. The permittivity increased as the BaFe12O19 content increased, whereas the dielectric loss decreased in the composite systems, which could be attributed to the variance in the formation of phases. At last, we suggested that further studies on magnetic properties should be considered for the application in electronic devices like LC filter.
