CERAMIC COMPOSITION FOR THERMISTOR TEMPERATURE SENSORS AND THERMISTOR DEVICE MANUFACTURED FROM SAID COMPOSITION

The present invention relates to a ceramic composition for thermistor temperature sensors used in DOC and DPF for removing nitrogen oxides, carbon monoxide, and uncombusted particles in an automotive exhaust gas system or for industrial use in a similar high temperature environment, and to a thermistor device manufactured from the composition, and more particularly relates to same being formed of a perovskite-phase element having a perovskite-type crystalline structure represented as ABO3, to which the 5B group element Sn and the 4B group elements Sb, Bi are added, where A is formed of at least one or more elements from the 3A group, with the exception of 2A and LA, and B is formed of at least one or more elements from 4A, 5A, 6A, 7A, 8A, 2B, and 3B, which are transition metals.
