| Abstract | ||
| One of the ternary oxides , like Cd2SnO4 powder was prepared by powder technology and press it as pellet of diameter 1.3 cm in order to study its structure and the behavior of complex dielectric constant and a.c. conductivity . Cd2SnO4 powder as bulk has polycrystalline structure as indicated by X-ray diffraction analysis (XRD) .Its structure has four strongest diffraction peaks as well as another peaks have different small intensities and plane of Miller indices (130) is the preferred orientation . The behavior of complex dielectric constant and overall response of conductivity for Cd2SnO4 as pellets were measured within frequency range 100 Hz to 10 MHz and temperatures range (298 – 453) K . It was found that the dielectric constant increases at lower frequency to a maximum value in a certain frequency then decreases with the increase of frequency . This peak shifts to higher value of frequency with the increase of temperature. Values of frequency exponent s for a.c. conductivity increases with the increase of temperature . Also values of activation energy increase with the increase of frequency. | ||
