| Abstract | ||
| In this research, pure and impure barium titanate with Zr4+ ion with two molar ratios x= (5, 10) % have been synthesized by solid-state reaction technique. The powders calculations at two temperatures (950°C and 1400°C). An XRD technique was used in order to study the crystal structure of pure and impure barium titanate, which confirmed the formation of the tetragonal phase of BaTiO3, then calculate the lattice parameters of pure and impure barium titanate, the addition of zirconium ion Zr4+ lead to increases lattice parameters. | ||
