Thermistor and method of fabricating.

摘要

A high temperature thermistor and its method of fabrication are disclosed. The thermistor is fabricated from titanium dioxide ceramic forming material and is fabricated to achieve a high degree of densification approaching 100% of theoretical density. At elevated temperatures in the range of from about 700 DEG F (350 DEG C) to about 1500 DEG F (825 DEG C) densified titania ceramic material behaves a semiconductor having a resistance which is responsive principally to the temperature of the thermistor element. The thermistor is fabricated by processing titania powder which includes a substantial majority of rutile phase material. The titania powder is processed to achieve a thermistor chip or member which demonstrates a high degree of density.
