На примере кристаллогидратов Zn(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O и Co(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O показано, что метод температурной истории может быть применен как дополнение к методу дифференциальной сканирующей калориметрии при измерении навески вещества массой от 5 до 30 г в условиях естественного охлаждения. Определено, что наилучшим методом расчета энтальпии кристаллизации является метод термической задержки. По результатам измерений определено, что энтальпия кристаллизации Co(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O составила 131.8 Дж/г, энтальпия плавления — 131.4 Дж/г. Энтальпия кристаллизации Zn(NO<sub>3</sub>)<sub>2</sub>·6H<sub>2</sub>O составила 128.9 Дж/г, энтальпия плавления — 157.4 Дж/г. Учет вклада теплоемкости в переохлажденной области, равного 16.9 Дж/(г °C), позволяет сделать вывод о корреляции этих двух величин.</p></abstract><trans-abstract xml:lang="en"><p/></trans-abstract><kwd-group xml:lang="ru"><kwd>гексагидрат нитрата цинка</kwd><kwd>гексагидрат нитрата кобальта</kwd><kwd>теплоаккумулирующие материалы</kwd><kwd>метод температурной истории</kwd><kwd>метод термической задержки</kwd><kwd>метод временной задержки</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российская академия наук</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Academy of Sciences</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Тестов Д.С., Моржухина С.В., Гашимова В.Р., Моржухин А.М., Кирюхина Г.В., Попова Е.С., Гасиев А.Л., Крюкова-Селиверстова А.В.
