Abstract

<p><strong>Abstract.</strong> In this work, it is shown how a finite element method (FEM) model of a Tian–Calvet calorimeter is used to find improvements in the sensor design to increase the sensitivity of the calorimeter. By changing the layout of the basic part of the sensor, which is a low temperature co-fired ceramics (LTCC) based sensor disc, an improvement by a factor of 3 was achieved. The model was validated and the sensors were calibrated with a set of measurements that were later used to determine the melting enthalpies and melting temperatures of indium and tin samples. Melting temperatures showed a maximum deviation of 0.2<span class="thinspace"></span>K while the enthalpy was measured with a precision better than 1<span class="thinspace"></span>% for most samples. The values for tin deviate by less than 2<span class="thinspace"></span>% from literature data.</p>
