Effect of calcining temperature on electrical and dielectric properties of cadmium stannate
چکیده انگلیسی
The cadmium stannate samples were prepared by chemical co-precipitation method using stannic chloride pentahydrate (SnCl4·5H2O) and cadmium chloride (CdCl2) as precursors by carefully controlling the preparative parameters. The effect of calcining temperature on the phase, microstructure, morphological and electrical properties of cadmium stannate has been investigated. The X-ray diffraction patterns indicate the conversion of rhombohedral to spinel cubic crystal structure and polycrystallinity of the samples. SEM study of Cd2SnO4 sample shows randomly distributed cubic crystals of varying sizes. The dc resistivity was measured as a function of temperature. The dielectric constant and dielectric loss were studied as a function of frequency. To understand the conduction mechanism in the samples AC conductivity was measured.
