    摘要： A sintered ceramic for high-stability thermistors is based on Ni.sub.x Mn.sub.3-x O.sub.4, where x>0. The sintered ceramic has the general formula Cu.sub.z Fe.sub.1-y Ni.sub.x Mn.sub.2-x-z+y O.sub.4, where z=0 to 1.5; y =-0.1 to 0.02; and 1>z>0.5. A method for producing a sintered ceramic for high-stability thermistors includes converting a mixture of starting materials MnO.sub.x, NiO and Fe.sub.2 O.sub.3 into a stable ceramic of an iron-nickel-manganese oxide spinel phase with high thermal stability and aging stability. Another method for producing a sintered ceramic for high-stability thermistors includes calcining a mixture of nickel carbonate, manganese carbonate and .alpha.-iron (III) oxide by heating to over 600.degree. C. in air. After granulometric preparation and compression molding, sintered ceramic bodies are produced by sintering in air or in an oxygen atmosphere.

    摘要： A high-temperature gas sensor for the detection of the heat tone of combustible gases includes a semiconducting ceramic layer with thermistor properties. The semiconducting ceramic layer is formed of an oxide ceramic semiconducting material having a defined crystalline structure and a thermistor characteristic of high sensitivity. A process for the manufacture of the high-temperature gas sensor includes sintering a loosely structured layer of powder particles of an oxide semiconductor with both a defined composition and high sinter activity for achieving a required high porosity of a semiconducting ceramic layer with thermistor properties.

    摘要： A CO.sub.2 sensor includes a body of solid electrolyte ceramic with alkali ion conductivity, and two electrodes of conductor material being inert with respect to the solid electrolyte ceramic. At least one of the electrodes is at least partially permeable, and the solid electrolyte ceramic is galvanically prepolarized. A measurement circuit configuration includes the CO.sub.2 sensor and a voltage measuring device coupled to the electrodes of the solid electrolyte ceramic body.
