Abstract: T he effects of sintering temperature, socking time, heating system and cooling method on compound heat-sensitive property of (PbSr) TiO₃-based ceramics is studied by cross experiment．It is shown that socking time is the key factor of effecting the smallest specific resistance, heat treatment in rising temperature process and cool temperature rate in cool process influence on the positive and negative temperature coefficient．

Key words: (PbSr) TiO₃-based ceramics, cross experiment, sintering system
