摘要： An electrochemical measuring sensor is proposed for determining the oxygen content in exhaust gases which has a base body made of an ion-conducting solid electrolyte in the form of a tube closed at one end, an inner electrode, an outer electrode disposed on the external surface of the probe block and having a conductor track on the connection side which has a covering layer, a ceramic protective layer and a metallic sealing ring for sealing the reference space from the exhaust gas space and for making an electrical contact to the housing in which the measuring sensor is to be inserted. The electrochemical covering layer covering the conductor track is brought down on the reference side of the probe block to below the metallic sealing ring and the track is formed with uncovered lateral extensions making electrical contact with the ring. This makes it possible to significantly prolong the service life of the measuring sensor.

摘要： A process is proposed which serves to produce layer systems for gas sensors, the electrodes essentially being composed of a finely divided ceramic material and finely divided electron-conducting material. The process comprises adding stabilizer oxides to the electrode material in proportions above those necessary for full stabilization. As a result, a layer system having outstanding mechanical properties and high electrode load carrying capacity is obtained by a simple manufacturing process.

摘要： A resistance probe is proposed for detecting gas compositions, particularly in the exhaust gases of internal combustion engines. This resistance probe has the advantage over prior art resistance probes that, with a short response time, it is considerably more aging resistant. This is accomplished in that the resistance layer configured as a semiconductor layer is introduced or sintered into recesses or slits provided for this purpose in the prefabricated sensor carrier body and above it is applied a porous, electrically non-conductive engobe or a protective layer structure in the form of a grid or raster. These measures enable the measuring gas to gain access to the semiconductor layer, but the semiconductor layer is simultaneously protected against corrosive, erosive and/or cavitative attacks from the exhaust gas.

摘要： A ceramic consisting substantially of Al.sub.2 O.sub.3 as ceramic support, ceramic cover layer and/or ceramic supporting structure for heating conductors is described, which is electrochemically stable, which, in other words, does not decompose on application of a heating voltage, even in long-term operation at temperatures above 600.degree.. Such a ceramic exhibits a very small alkali metal content, of less than 0.2% by weight Na.sub.2 O and K.sub.2 O respectively. Particularly favorable processing, in particular pressing properties are exhibited by such a ceramic if it has 2.5 to 10% by weight of barium silicate or strontium silicate fluxes, the proportions of Na.sub.2 O, K.sub.2 O, CaO and MgO together make up less than 1% by weight, and the BaO or SrO:SiO.sub.2 molar ratio is between 2:1 and 1:12.5. Such a ceramic with a BaO:SiO.sub.2 ratio of 2.6:1 parts by weight is electrochemically stable up to approximately 1400.degree. C., and at 1300.degree. C. still exhibits a bending strength of approximately 300 N/mm.sup.2.

摘要： In order to obviate the necessity for design compromise of spark plugs with respect to their operating temperature, so that the ceramic insulator (18) of the spark plug will rapidly reach the temperature at which deposits thereon will inherently burn off (about 400.degree. C.-450.degree. C.) while not becoming so hot as to cause spurious glow ignition within the combustion chamber of an internal combustion (IC) engine, the end portion of the insulator is formed with a central opening (19/3) within which a metal core (24) is included which has a temperature coefficient of expansion such that, at temperatures below between 400.degree. C.-450.degree. C. it is spaced by a narrow gap (25) from the inner surface of the insulator (see FIG. 1) but, as the spark plug becomes hot, the gap 25 closes (FIG. 2), thereby providing good heat transmission from the insulator to the center electrode structure (21, 23, 24) and thereby maintaining the insulator at a temperature below that at which it might glow. Suitable materials for the center electrode are aluminum bronze, or other materials having a heat transmission characteristic of at least 90 W/mK. The insulator, preferably, has a higher-than-usual flux content so that, at low temperatures, its heat transmission characteristics are poor, to insure rapid heating to free combustion temperature of possible deposits.

摘要： To improve response time and provide an electrode which has good adhesion to a solid electrolyte body, typically of zirconium, to be used in lambda sensors or polarographic current limit sensors, and additionally enhance the loading capability thereof, the pre-sintered or fully sintered solid electrolyte body, typically of zirconium dioxide, has an electrode layer applied thereto on which, in advance of sintering thereof, a cover layer is applied which, when sintered, develops pores. The cover layer is a ceramic material, sintered together with the electrode on the solid electrode body. This results in higher loading capability and decrease in response temperature to about 250.degree. C. The sensors can be used as lambda sensors and polarographic current sensors, to determine oxygen content in exhaust gases, typically for automotive engines, as well as in high-temperature fuel cells, high-temperature batteries, and high-temperature electrolysis cells.

摘要： Glass powder is wetted with an aqueous solution or emulsion of an organic binder and mixed with carbon black in the form of soot or lampblack. The resulting material is packed between the parts of the central electrode of a sparkplug and fired at a temperature sufficient to fuse the glass to produce a gas-tight seal with electrically conducting properties. Up to 5% of metal powders may be included in the material if it is desired to prevent the resistance from rising during service. Oxides or carbides and certain other metal powders may be added to bring the thermal expansion coefficient to a desired average value.
