Two Co\u2013C eutectic fixed points were constructed for thermocouple calibration. The eutectic fixed points were measured with a Pt/Pd thermocouple calibrated at the freezing temperatures of Sn, Zn, Al, Ag, and Au. A temperature of (1323.99 \ub1 0.52)\u25e6C(k = 2) was determined via thismethod. The cell design allowed filling to be accomplished in a single step. Each cellwas held above 1300 \u25e6C for at least 42 h and was subjected to at least 20 melt/freeze cycles with no mechanical failure occurring.abstractPeer reviewed: YesNRC publication: Ye
