Title:
POSITIVE CHARACTERISTIC THERMISTOR
Document Type and Number:
WIPO Patent Application WO/1994/024680
Kind Code:
A1
Abstract:
A thermistor having a small specific resistance rho25 at room temperature, a large alpha and stable characteristics. The semiconductor which constitutes the main body of the thermistor is a BaTiO3 perovskite-type compound. The quantity of Ti is smaller than that determined by the stoichiometric ratio, which has been preferably in excess conventionally.
