ZrO2 substituted polycrystalline BaTi2O5, Ba(Ti1−yZry)2O5, (BT2Z), was prepared by arc-melting and the dielectric property was investigated by AC impedance spectroscopy. The length of a-axis increased from 1.6895 to 1.6952 nm and that of c-axis increased from 0.9411 to 0.9436 nm with increasing y up to 0.06. The b-axis was almost independent of ZrO2 content. The solubility limit of ZrO2 (y) in BT2Z can be 0.06. BT2Z had a strong b-axis orientation at y<0.06. The permittivity of BT2Z at y=0.005 showed the highest peak of 3050 at 725 K and the peak temperature decreased from 750 to 465 K with increasing y from 0 to 0.064. A relaxor-like frequency dependence of permittivity was observed at y>0.06.
