Abstract

The Mise-en-Pratique for the definition of the kelvin at high temperatures has opened the possibility of disseminating thermodynamic temperature through relative primary radiometry mediated by high-temperature fixed points (HTFPs). The thermodynamic temperatures of Co-C, Pt-C and Re-C were assigned in 2016. Here, we report on the assignment of thermodynamic temperatures of the phase transitions of four more HTFPs, namely, Fe-C ~1427 K, Pd-C ~1765 K, Ru-C ~2227 K and WC-C ~3020 K, with expanded uncertainties ranging from 0.15 K to 0.27 K.
