Abstract
The possibility of using beryllium as a means of storing and transferring a unit of specific heat capacity and extending the range of values of heat capacity measures from 1654 to 2900 J/(kg·K) towards the upper limit is estimated. The temperature dependence of the specific heat capacity of beryllium samples of known composition in the temperature range of 260–870 K has been determined. The reproducibility of the thermophysical properties of beryllium over time and under repeated heating in the specified temperature range is analyzed. The results obtained are relevant for the field of metrological support in the field of measurements of thermophysical quantities.
