Disclosed are means and method for forming elastic connection between ceramic and metallic structural elements. The means comprises a ceramic structural element; a metallic structural element having thermal and elastic properties different from those of the ceramic structural element; and a connecting element connecting the ceramic and metallic structural elements and comprising an insulating resilient body of ceramic material having a thermal conductivity of between about 0.02 and 0.25 W/cmK at a temperature difference between the ceramic and metallic structural elements of from about 100 to 1500 Centigrade degrees, an elastic modulus of between about 5000 and 150,000 N/mm.sup.2 and being substantially free of plastic deformation.

Element and method for connecting ceramic and metallic parts

The invention relates to a recuperative heat exchanger comprising an elongate rotationally symmetric body of ceramic material having radially outwardly extending, flow channels of slot like cross-section extending along the axis of the body. Alternate flow channels extend further toward the surface of the body and further toward the axis of the body, respectively. Inlet and outlet openings are provided for the flow channels about at the ends of the body. The invention also comprises a process for making such a heat exchanger, including extruding ceramic material through an extrusion nozzle with a free cross-section in which core bodies are shaped and positioned for generating the flow channels and inner and outer cover walls defining the flow channels. The invention further comprises the extrusion nozzle in which the process is performed.

Recuperative heat exchanger of ceramic material

Disclosed is a recuperative heat exchanger, comprising a body of ceramic material having a plurality of generally parallel flow channels arranged adjacently to one another generally axially with respect to the body, with adjacent flow channels having a common partition wall. The plurality of flow channels include a plurality of first flow channels for carrying a first heat transfer medium and a plurality of second flow channels, alternatingly arranged with respect to the first flow channels, for carrying a second heat exchange medium. Each of the first channels has an inlet positioned on one lateral side of the body near a first longitudinal end of the body and an outlet positioned in the opposite, second longitudinal end of the body, and each of the second flow channels has an inlet positioned on one lateral side of the body near the second longitudinal end of the body and an outlet in the first longitudinal end of the body. Also disclosed are several processes for manufacturing the disclosed heat exchangers.

Heat exchanger and process for its manufacture

Refractory products such as foundry articles and composite metal-ceramic articles are prepared from a sepiolite (2 MgO.3SiO.sub.2.2H.sub.2 O) and silicate containing aluminum titanate.

Refractory articles and composite metal-ceramic articles (cermets)

A heat exchanger of a ceramic body, or the like, having a plurality of elongate flow passages in parallel relationship with the placement of the passages staggered with respect to the opposite end cover walls of the ceramic body, transversely extending parts of both cover walls being absent to expose those staggered passages that pass closer to the respective cover wall, thereby to permit access for fluid media to the flow passages; particular characteristic features of the passages are disclosed.
