COMPARISON OF DIFFERENT METHODS OF FIXED-POINT TEMPERATURE EVALUATION

Gunter Krapf, Marc Schalles

Abstract

The estimation of the fixed-point temperatures <i>T</i>_ph from measured plateau curves can be carried out using different mathematical methods. Depending on the method used and the size of the fixed-point cell, different systematic deviations and reproducibilities of the calculated temperatures arise. They typically develop during the evaluation of measurements from small fixed-point cells. Thus the phase transformation temperatures of miniaturised fixed-point cells with zinc of different purities were measured and five different methods were compared.
