Study of electrical conduction behaviour of Y6-xBa4(SiO4)6O2 oxyapatite doped with ytterbium ions

Abstract

Abstract This paper reports the electrical conduction behaviour of Yttrium Barium Silicate Oxyapatite Y6-xBa4Ybx(SiO4)6O2, synthesized by solution combustion method where x varies from 0.01 mol% to 0.05 mol%.. The scanning electron microscopy was done for morphological analysis which shows the spheroidal shaped grains with average grain size of 35μm. The dielectric behaviour of the material was studied in the frequency range of 100Hz – 100KHz and temperature varying from 50°C - 400°C. The frequency dependent dielectric constant and dielectric loss has been plotted for different temperatures. Decrease in dielectric constant and dielectric loss with increase in frequency has been observed for YBaSiO:Yb compounds.
