Abstract
1,041,689. Thermocouples. NORTON CO. Aug. 13, 1965 [Sept. 25, 1964, No. 34711/65. Heading H1K. The arms of a thermocouple are formed integrally by sintering doped silicon carbide particles. The thermocouple may be formed in the shape of a rod with the junction in the middle, Fig. 1 (not shown), by placing particles of P-type silicon carbide doped with aluminium, boron, gallium or indium in one half of a mould, placing particles of N-type silicon carbide doped with nitrogen, phosphorus, arsenic or antimony in the other half of the mould, and then compressing and sintering. Since the material is somewhat porous it may be formed in the shape of a tube through which an inert gas such as argon is passed to purge the device. As shown, Fig. 2, the two arms of the thermocouple may be arranged concentrically, the inner arm 17 being supported at intervals by insulators (not shown). The junction 21 is entirely enclosed but if necessary the device may be hermetically sealed by surrounding it with an impervious enclosure or coating. Alternatively inert gas at a higher pressure than the external ambient may be forced into the closed tube so that it diffuses out through the porous structure to protect the device. The connections to the cold ends of the thermocouple can be made by soldering, welding or mechanical clamping. The impurities may be introduced into the silicon carbide particles during or after growth or may be diffused into the structure after it has been sintered or at another stage of manufacture. Different concentrations of the same impurity may be used to form the arms of the device. More than one interfacial region may be provided.
