摘要： The invention relates to a green ceramic insert (20) comprising a green ceramic body (14) provided with a recess (15). Said recess (15) crosses the ceramic body (14) and is filled with a paste (15') which can be converted into an electrical feedthrough. The invention also relates to a ceramic insert consisting of a sintered insert (20) of the same green ceramic type. The invention further relates to a ceramic green body (5) or a green body composite (5') which comprises at least one recess (11), in areas, in which one of the above-mentioned green ceramic inserts (20) is placed. Disclosed is also a ceramic laminated composite consisting of a sintered green body (5) or green body composite (5')of the same green ceramic type. According to the invention, the ceramic insert (20) is especially connected to the laminated composite in a material fit. A conductive paste (16) which is converted into a strip conductor by means of sintering is guided on the laminated composite in such a way that it is electrically insulated from the same. Said ceramic insert connects the upper side of the laminated composite to the lower side thereof in an electroconductive manner by means of the electrical feedthrough.

摘要： The invention relates to a sensor element for a gas sensor for determining the physical property of a test gas, particularly the concentration of a gas constituent in the exhaust gas of internal combustion engines. The sensor element comprises an, in particular, laminated ceramic body (11) with a test gas space (12) that is in contact with the test gas via a diffusion barrier (21). In order to obtain a gas permeability of the diffusion barrier (21) that is necessary for a controlled gas diffusion within narrow manufacturing tolerance limits so that a subsequent trimming or calibration of the manufactured sensor element can be eliminated, cavities are formed in the diffusion barrier (21) in a defined geometric order. The cavities are preferably provided in the form of fine branched channels (30) on the scale of micrometers that, due to their shape and arrangement, enable the desired gas permeability to be determined in a highly precise manner.
