Electrical properties of binder-free thick film BaYxBi1−xO3 NTC thermistors

A novel (1−x)Ba 0•7 Bi 0•3 Fe 0•9 Sn 0•1 O 3-xBaCo II 0•02 Co III 0•04 Bi 0•94 O 3 (0•2 ≤ x ≤ 0•9) negative temperature coefficient (NTC) thick film thermistors with high thermistor constant was prepared by screen printing. The values of room-temperature resistivity, thermistor constant and activation energy of the thick film thermistors, increasing with the addition of Ba 0•7 Bi 0•3 Fe 0•9 Sn 0•1 O 3 , are in the range of 35•5 •cm-1•34 M •cm, 2067-6139 K and 0•177-0•527 eV, respectively. This means that the electrical properties of the thick films are adjustable at a wide range, depending on the compositions. Impedance analysis shows that the magnitude of thick film bulk resistance is mainly attributed to the contribution of grain boundary.
