Abstract: The invention relates to a sensor housing, which has a base body (10) and a media contacting cap (20). The media contacting cap (20) is arranged partially in a recess (11) of the base body (10) in a detachable manner. It has an annularly running recess (21) for partially receiving a sealing element (60) for a metal clamp connection. Furthermore, the invention relates to a sensor. This has a measuring element (30), which is arranged in the media contacting cap (20) of the sensor housing.

Abstract: The process of the invention characterized in that to 100 parts by weight of a silicate powder having 2000-8000 m2/g specific surface, 1-10 parts by weight of gas-forming material with particle size of 10-100 &mgr;m and 0.5-15 parts by weight of montmorillonite, 0.5-2 parts by weight of alkali hydrogen phosphate or alkali dihydrogen phosphate or a mixture of alkali metal phosphate and sodium silicate in form of aqueous solution, 0.01-5 parts by weight of rare earth metal oxide or a mixture of such oxides were added, then the mixture obtained is homogenized, pre-dried, coated with 1-5 parts by weight of titanium oxide and/or titanium oxide hydroxide and/or aluminum oxide hydroxide, then subjected to heat treatment at 720-1000° C., and the mixture obtained is molded. The subject of the invention: also the product of the above process.
