Although the temperature stability and uncertainty of the freezing plateau is better than that of the melting plateau in most of the thermometry fixed points, but realization of melting plateaus are easier than that of freezing plateaus for metal fix

Thermoelectric inhomogeneity is the spatial variation of the Seebeck coefficient along a thermoelement. It is often considered to be the largest contribution of an uncertainty budget in thermocouple calibration. In this work, investigations of inhomo
