DEVELOPMENT OF METAL-CARBON EUTECTIC CELLS FOR CONTACT THERMOMETRY AT KRISS

Yong-Gyoo Kim, Inseok Yang
  • Abstract:
    We report the status of development of metalcarbon eutectic cells for contact thermometry at KRISS. Up to now, Co-C, Ni-C, Fe-C and Pt-C eutectic cells have been fabricated and their performance has been tested. The uncertainty of Co-C melting point using a Type B thermocouple was 0.9°C (k = 2). The melting plateau of the Fe-C eutectic cell has shown a dependence on the prefreezing set temperature.
