Проведены исследования температурной зависимости удельной теплоёмкости образцов бериллия известного состава в диапазоне температур 260–870 К. Проанализирована воспроизводимость теплофизических свойств бериллия во времени и при многократном нагреве в указанном диапазоне температур. Полученные результаты актуальны для сферы метрологического обеспечения в области измерений теплофизических величин.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бериллий</kwd><kwd>удельная теплоёмкость</kwd><kwd>эталонная мера</kwd><kwd>метрологические характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beryllium</kwd><kwd>specific heat</kwd><kwd>reference measure</kwd><kwd>metrological characteristics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ginn ings D.
