抄録

High temperature fixed-points based on eutectic alloys of metals and carbon have been proposed as secondary reference points for the International Temperature Scale of 1990. These allow checks of thermometry with a precision rivalling the uncertainties of many National Measurement Institutes. Aspects of the construction of such fixed-points are considered with guidelines for making fixed-points that have best performance.
