Abstract

Sr2Ce2Ti5O16 ceramics filled PTFE composites were prepared by powder processing technique. The structure and microstructure of the composites were investigated by X-ray diffraction and scanning electron microscopic methods. The effect of Sr2Ce2Ti5O16 ceramic content (0–0.6 volume fraction) on the dielectric properties of the composites was studied at 1 MHz and 7 GHz. The dielectric constant and dielectric loss increased with the increase of Sr2Ce2Ti5O16 content. The measured dielectric constant (ɛr) is compared with the effective dielectric constant calculated by Lichtenecker, Maxwell-Garnet, Jayasundere, Poon-Shin formulae and Effective Medium Theory. The observed dielectric constants are reasonably in good agreement with that calculated using Effective Medium Theory.
