Abstract

In this study, the physical and thermoelectric characteristics of glass-ceramic materials are examined to provide the thermoelectric performance of 30Li2O: 3MoO3: 40Bi2O3: 20TeO2: 7CuO samples that were synthesized utilizing the melt-quenching process. Archimedes' Principle was used to determine the physical properties of the sample, showing a density of 4.53 g/cm3. An X-ray diffractometer (XRD) used to analyze the crystal structure revealed the Bismuth Oxide phase. The results of measuring with the LCR Meter for the frequency range were set from 50 Hz to 1 MHz at room temperature, showing the dielectric constant (ε’) and the dielectric loss (ε”) that tended to decrease with increasing frequency. Thermoelectric properties were examined in a temperature range of 300 K to 600 K indicating the electrical resistivity, the Seebeck coefficient, and the power factor. By calculating the efficiency of thermoelectric materials, the power factor term is considered at which temperature it shows its highest value. In this work, it was shown on 6.99 mW/mK2 at a temperature of 474 K
