Pb (Zr0.52Ti0.48)O3, (PZT) powder has been synthesized using high energy ball milling technique. The synthesized powders were characterized using XRD, SEM, Density, Porosity and Impedance Analyzer. XRD patterns show that the perovskite phase of PZT can be formed from the mixture of starting material after milling for 40 h. The grain sizes of the powder have been estimated to be 1-3 μm. The relationship between the microstructure of the PZT samples and sintering temperature has been discussed. Dense PZT (> 95 % theoretical density) with excellent dielectric properties was obtained when the pellet are sintered at higher temperature with shorter soaking time. The results show that the sample sintered at 1100 °C /1 h yields a clearly uniform grain size with the highest dielectric constant.

Polymer-ceramic composites have been pursued as the most promising dielectric materials for embedded capacitors in the organic package. In this study, ceramic fillers such as Calcium Copper Titanate (CCTO) was used to produce epoxy thin film composites for the purpose to replace capacitor made of ceramic materials. Spin coating technique was used to produce epoxy thin film composites. The effect of fillers loading on tensile and dielectric properties of the epoxy thin film composites were determined. Results showed that epoxy thin film with 20 vol% filler loading showed good dielectric properties. However, an increase of the fillers content caused reduction in the tensile properties due to filler agglomeration and voids. Dielectric constants and dielectric losses of epoxy/inorganic composite films generally increase with addition of filler.
