Abstract
:
Seven samples of lead molybdenum phosphate glasses are prepared due to mol % composition PbDx MoO3 (80 – x) P2O3(20) over the compositional ranges from x = 0 to 60. The microwave behavior of this kind of glasses is investigated in term of the microwave dielectric properties measurements at low temperature due to lead addition. The full computerized cavity perturbation technique working in microwave frequency ranges 615 MHz, 1412 MHz, 2214 MHz, 3017 MHz, and 3820 MHz are used for these measurements. The real ' and the imaginary '' parts of the complex permittivity are measured at room temperature and the frequency-dependent electrical conductivity is calculated using the complex permittivity imaginary part ''. The frequency exponent n and the activation energy EA are determined using the calculated electrical conductivity . Microwave absorption is observed on the sample consisted of molybdenum and phosphate rather than the other samples with lead addition.
