Abstract

Nano-structural ZnO of unique electrical and optical properties is highly attractive in dielectric and microwave applications, specifically considered as ideal fillers for achieving light-weight composites. In this work, tetra-needle ZnO (T-ZnO) by a direct combustion approach was selected as the filler in silica nanopowders for fabricating T-ZnO/SiO₂ composites. Temperature effects on dielectric properties of the composites were investigated in the temperature range of 300-700°C at 8.2-12.4 GHz. The observed imaginary permittivity and loss tangent was found to be temperature dependent, and the mechanism associated with relaxation and electrically conductive loss was discussed.
