Abstract

The electric properties of BaTiO₃-(Bi₁/ ₂A_1/2)TiO₃ (A=Na, K) solid solution ceramics were studied as a lead-free PTCR (positive temperature coefficient of resistivity) thermistor material usable over 130°C. For determining the maximum switching temperature T_s, the phase diagrams of BaTiO ₃-(Bi₁/₂Na₁/₂)TiO ₃ (BT-BNT) and BaTiO₃-(Bi1/₂K1/ ₂)TiO₃ (BT-BKT) binary system were clarified. We obtained lead-free PTC materials with a low resistivity at room temperature (PRT) and high temperature coefficient (a) by sintering the ceramics in a low O ₂ containing atmosphere.
