摘要： This invention provides a reducing-atmosphere-resistant thermistor element, the resistance of which does not greatly change even when the element is exposed to a reducing atmosphere, and which has high accuracy and exhibits excellent resistance value stability. The thermistor element has a construction in which an oxygen occlusion-release composition, having oxygen occlusion-release characteristics, such as CeO2 is dispersed in a composition containing a mixed sintered body (M1 M2)O3.AOx as a principal component. The oxygen occlusion-release composition emits absorbed oxygen in a reducing atmosphere and suppresses migration of oxygen from the composition constituting the element. Therefore, the resistance value does not greatly change even when the element is exposed to a reducing atmosphere, and the element can accurately detect the temperature for a long time. The present invention can thus provide a temperature sensor having high reliability.

摘要： Thermistor elements composed mainly of a metal oxide sintered body are prepared by mixing a metal oxide precursor in a liquid phase to prepare a solution or slurry of the precursor. The precursor solution or slurry is sprayed to form droplet particles which are heat treated to form a thermistor raw material powder which powder is then molded and sintered into a shape to provide a metal oxide sintered body.

摘要： A temperature sensing element includes a thermistor composed of Si-base ceramics and a pair of metal electrodes bonded onto the surfaces of the thermistor. The metal electrodes contain Cr and a metal element α having a Si diffusion coefficient higher than that of Cr. A diffusion layer is formed in a bonding interface between the thermistor and each metal electrode, the diffusion layer including a silicide of the metal element α in a crystal grain boundary of the Si-base ceramics. A temperature sensor including the diffusion layers is provided. Owing to the diffusion layers, the temperature sensor ensures heat resistance and bonding reliability and enables temperature detection with high accuracy in a temperature range, in particular, of from −50° C. to 1050° C.
