摘要：

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 beta = 103.12(6)degrees. 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.
