| dc.description.abstractEn | The present work reports the elaboration and physical investigation of new compounds of the following composition Ba<sub>1−<i>x</i></sub>Na<sub><i>x</i></sub>(Ti<sub>1−<i>y</i></sub>Sn<sub><i>y</i></sub>)<sub>1−<i>x</i></sub>Nb<sub><i>x</i></sub>O<sub>3</sub> (BTSnN<i>xy</i>). The studied ternary system presents some continuous solid solutions between the next 3 phases: the NaNbO<sub>3</sub> antiferroelectric phase that becomes easily ferroelectric at low rate substitutions, the BaTiO<sub>3</sub> ferroelectric phase and the paraelectric stannate phase BaSnO<sub>3</sub>. Two different dielectric behaviors can be observed once some substitutions are made either in A or B sites of an ABO<sub>3</sub> perovskite. These substitutions modify the dielectric properties of the material. The introduction of Sn<sup>4+</sup> and Ti<sup>4+</sup> cations in the B site favors, respectively, a decrease of the transition temperature and an increase in the value of the real dielectric permittivity. The transition temperature should be modulated by varying the rate of cationic substitution. Some relaxor materials can be obtained at a temperature around room temperature. | |
