摘要：

Sr0.2Ba0.8Nb2O6 ceramics with 1 mol% V2O5 addition were fabricated by liquid phase sintering. A compact sintered at 1300 degrees C for 100h had the spontaneous polarization of 6.1 x 10(-2) C/m(2) at 50 degrees C. The sharp permittivity peak was observed at 293 degrees C, corresponding to the Curie temperature. The crystal structure had the orthorhombic symmetry with a(0)=1.7654, b(0)-1.7662 and c(0)=0.7961 nm at room temperature. The orthorhombic-tetragonal phase transition was found at about 120 degrees C.
