Title: Method of manufacturing negative temperature coefficient thermistor device
Inventor: CHIYOUSOKABE TAKAAKI
IPC: H01C7/04
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an NTC thermistor device which keeps a stable and low B constant at high temperature or in an oxygen- free atmosphere without changing its composition. SOLUTION: This method of manufacturing an NTC thermistor device comprises a first thermal treatment of thermally treating a device which contains a component formed of (Y, Sr) (Cr, Fe, Ti)O3 at temperature of 1,100 deg.C or higher put below 1,400 deg.C for 30 hours after the device has been baked, and a second thermal treatment of thermally treating the device which has been subjected to the first thermal treatment at temperatures of 800 to 1,100 deg.C for 30 hours or above. The NTC thermistor device obtained through the above method is capable of remarkably decreasing its B constant especially in a low temperature range, showing a resistance value and expanding a range of resistance change in the lower temperature range.  Its resistance change rate is 6% or below at various levels of temperature ranges, and the device displays stable temperature characteristics of resistance even under severe conditions that the device is embedded in the heat sensing part of a sensor where metal is quickly oxidized and corroded.
