摘要： An electrical foam heating element made by the process of forming a volume of reticulated silicon carbide foam material into a preferred shape, heating the material to a temperature of about 1000.degree. C. for a period of 24-30 hours, forming conductive edges over two respectively facing edge surfaces, applying an electrically-conductive felt material against the respective conductive faces, and clamping foam volume and foam between two electrically-conductive electrodes. In another embodiment, a region of nickel foam material is provided between the respective electrodes and the silicon carbide interior, and intermediate felt layers are provided between the nickel foam and the silicon carbide foam, and between the nickel foam and the electrodes. The layered felt material is of three-layer construction: inner and outer layers of electrically-conductive felt separated by an interior metal foil layer.

摘要： A heating element comprises a body provided by fibrous tubes of an electrically conductive material, a voidage between the tubes providing a path for a fluid to be heated. The material may be silicon, silicon carbide, or silicon rich-silicon nitride. The heating element is manufactured by coating a fibrous carbon precursor with the material, and heating the coated precursor in an oxidizing environment so as to remove the carbon precursor by oxidation. The heating element has one application for a heat transfer system for controlling the temperature of a hot working device. The system comprises a fluid circuit including the hot working device, the heating element through which the fluid is driven by a pump, and a temperature controller for sensing the temperature of the device and controlling the temperature of the heating element as a function of the device temperature.

摘要： A coherent shape of silicon carbide is produced by heating particulate silicon carbide to a temperature above 3,000* F. and below 5,500* F. and subsequently cooling the silicon carbide below 3,000* F., both steps being completed within a period of 30 minutes. In the preferred method, the particulate silicon carbide is exposed to the energy of a laser beam, and the particulate silicon carbide has a minimum particle size greater than ten microns. The preferred shape has a core with a relatively low resistivity of the magnitude of the order of 0.05 to 100 ohms per linear inch and a distinctly delineated rind with a relatively high resistivity which may be removed if lower thermal mass is required by a specific application.
