Effect of Dy2O3 on the structure and electrical properties of (Bi0.5Na0.5)0.94Ba0.06TiO3 lead-free piezoelectric ceramics

“…In order to characterize the dielectric dispersion and diffuseness of the phase transition, the modified Curie-Weiss law is proposed by many researchers [48][49][50]:…”

Elaboration and dielectric study of ferroelectric or relaxor ceramics in the ternary system BaTiO3–NaNbO3–BaSnO3

“…The values of T C = 468 K, T 1 = 240 K and T 2 = 320 K, were independent from frequency. For BaTiO 3 , these temperatures have been observed at T C = 393 K, T 1 = 268 K and T 2 = 183 K [19,20]. For the relaxor compounds like BTSnNxy (x = 0.60, y = 0.10), we only observe the relaxor/paraelectric transition at T m .…”

Effect of Ni doped BaTiO3 on the dielectric properties in the Ba(Ni1/3Nb2/3)xTi1−xO3 solid solution

“…In addition, for our material the value of the maximum of ε r is approximately the same as BaTi 1−x (Zn 1/3 Nb 2/3 ) x O 3 , but it is less than Ba(Fe 1/2 Nb 1/2 ) x Ti 1−x O 3 because of conductivity contribution in this latter system. If we compare these results to those obtained in Ba(Nb x Ti 1−x )O 3 in which the relaxor character was [11] 0 ≤ x ≤ 0.05 0.075 ≤ x ≤ 0.2, 0.75 ≤ x ≤ 0.975 Ba(Fe 1/2 Nb 1/2 )xTi1−xO3 [12] 0 ≤ x < 0.125 0.125 ≤ x < 0.15 obtained for compositions larger than ≈6% [13], we can deduce that the appearance of relaxor effect in our material is not due only to the substitution Ni but it can be caused by the Nb.…”
