Abstract

Poly- and single-crystalline BaTi₂O₅ co-substituted with SrO and ZrO₂, Ba_0.99Sr_0.01(T _1-xZr_x)₂O₅ (BT₂SZ) were prepared by arc-melting and floating-zone (FZ) melting, respectively. The specimens showed a significant (020) orientation. The highest permittivity of poly-crystalline BT₂SZ was 3880 at x = 0.005 and that of single-crystal was 27000 at x = 0.005. The Curie temperature (T_c) of poly-crystals decreased from 750 to 640 K with increasing x from 0 to 0.026 and that of single-crystals decreased from 750 to 710 K with increasing x from 0 to 0.008. The highest remnant polarization of single crystalline BT₂SZ was 7.8× 10^-2 Cm^-2 at x = 0.008, higher than that of the poly-crystal.
