| Abstract | ||
| Nanocompound of , and nanocomposite were prepared by Sol-gel method with a ratio x= 10, 25, 50, 75%. The samples compressed as a tablet under hydraulic pressure, and these tablets were sintered at a temperature of 900 ℃ for a period of two hours (2h). The X-ray diffraction revealed the hexagonal structure of with lattice parameters and , while reveals the cubic structure with a lattice parameter . The grain size of the samples has been calculated by SEM and it was between (25-35) nm. Electrical properties showed a decrease in the dielectric constant values, loss coefficient from (282.4348),(73.0997) to (4.2752),(0.4322) respectively, and increasing the electrical conductivity value from (2.2023*10-7 Ω-1 cm-1) to (9.1754*10-1 Ω-1 cm-1) with increasing the frequency. | ||
