Abstract

Single crystalline BaTi2O5 was prepared by a floating zone method. The single crystal was transparent having a (001) cleavage plane. The space group was C2, and the lattice parameters were a=1.6909(9) nm, b=0.3937(1) nm, c=0.9419(4) nm and β=103.12(6)°. The permittivity perpendicular to a (010) plane showed the maximum value of 20500 at 748 K. The permittivity perpendicular to (100) and (001) planes were about 140 and 70, respectively, independent of temperature.
