Huther, W

A thermocouple is made of the silicon carbide and carbon. A carbon rod extends within a silicon carbide tube. The tube is closed at one end, and one end of the rod is fixed in a blind hole in the tube end to define the hot junction of the thermocouple, the hot junction thereby being located within the tube. An electrical insulator sealing ring closes off the opposite end of the tube. The tube is made by sintering a preform, the rod being within the tube, with one end in the blind hole, during sintering, so that the hole wall shrinks around the rod end.
