Communication—Detection of Giant Dielectric Constant in Strontium Orthovanadate Sr3V2O8

In this work, we present a dielectric study on the Sr3V2O8 (SVO) ceramic matrix in the radiofrequency spectrum by using Impedance Spectroscopy (IS). We calcined pure phase SVO through the conventional solid-state reaction at 950°C and sintered the ceramic pellet at 1050°C. In the analyzed by X-ray Diffraction, the SVO presented single phase. At the Scanning Electron Microscopic (SEM) study, the micrographs presented a dense SVO with discrete large grains. The IS study was performed varying the temperature and showed that SVO presents giant relative dielectric constant (ɛr) not only at room temperature but also in high temperatures.
