Abstract
Sr0.2Ba0.8Nb2O6 ceramics with 1mol% V2O5 addition were fabricated by liquid phase sintering. A compact sintered at 1300°C for 100h had the spontaneous polarization of 6.1×10-2C/m2 at 50°C. The sharp permittivity peak was observed at 293°C, corresponding to the Curie temperature. The crystal structure had the orthorhombic symmetry with a0=1.7654, b0=1.7662 and c0=0.7961nm at room temperature. The orthorhombic-tetragonal phase transition was found at about 120°C.Keywords
