In order to elucidate the correlation between the relaxor type of phase transition and the percent of the A and B site substitution in the Ba1−xNax Ti1−xNbxO3 solid solution, the dielectric permittivity was carried out in the temperature range 80–600 K. All ceramics of these solid solutions present a ferroelectric–paraelectric phase transition with relaxor and classical character depending on the value of x.
