In Ba(Ti<1-x>Sn_x)O_3 solid solution, for Sn Concentration x ≤ 0.1, the permittivity follows the Curie-Weiss law above the Curie point T_c. The increase in the peak value of the permittivity at T_c is due to the change in ferroelectric transition from first order to second order with increasing x. For x > 0.1, some deviations from the Curie-Weiss law are observed in a narrow temperature region above T_c. The diffuse phase transition was observed. for x > 0.2, the Curie-Weiss law does not hold over a wide temperature range. The dielectric dispersion was observed in the ratio-frequency range (10 kHz-10 MHz). With increasing Sn concentration, the change in the phase transition from a normal ferroelectric transition to relaxor through the diffuse phase transition was observed.
