Dielectric Behavior Investigation of Composite Materials Based on Epoxy Resin/Fe3O4/CaTiO3, SrTiO3 Using Mixture Laws

Abstract

In the same matrix of epoxy resin, Fe3O4 powder was evenly mixed with one of two titanate powders, CaTiO3 or SrTiO3. The dielectric properties of these blends were evaluated using the measurement technique of time domain spectroscopy (TDS). During this work, low-frequency analyzes (DC − 300 MHz) were carried out, mainly focusing on the static permittivity and conductivity properties as a function of titanate concentrations. The results allowed us to confirm the validity and effectiveness of the modified Lichtenecker Laws (MLL). Significant agreement accord can be shown between the MLL-calculated and experimentally determined permittivity values for ternary combinations. The perspective of this research lies in the production of new materials for use in the field of telecommunications and in particular for microelectronic components.
