Abstract :
The melting points of Cr3C2-C peritectic (1826degC) and Cr7C3-Cr3C2 eutectic (1742degC) alloys were investigated as high-temperature fixed point cells for thermocouple calibration. Pre-tests were performed to establish a suitable procedure for the construction of contact thermometry cells based on such chromium-carbon mixtures. Two cells were constructed following two different possible procedures. The two above melting points were successfully observed for one of these cells using tungsten-rhenium alloys thermocouples.
