Калориметрическое определение фазовых переходов соединений Ag8ВX6 (B = Ge, Sn; X = S, Se)
Аннотация
Методом дифференциально-сканирующей калориметрии (ДСК) исследованы тройные соединения Ag8GeS6, Ag8GeSe6, Ag8SnS6 и Ag8SnSe6, имеющие полиморфные превращения при относительно низких температурах. Были исследованы два образца каждого соединения с различными массами навесок в интервале 20-40 мг, для которых были сняты по три кривых ДСК нагревания. На основании данных кривых ДСК определены температуры и энтальпии фазовых переходов исследуемых соединений от низкотемпературной ромбической модификации к высокотемпературной кубической. Данные ДСК для каждого образца на всех кривых нагревания отличались не более чем на 2 %. Из полученных данных были рассчитаны энтропии фазовых переходов и показано, что эти значения являются аномально высокими. Также был проведен сравнительный анализ полученных термодинамических данных для соединений Ag8GeSe6 и Ag8SnSe6 с результатами, полученными методом электродвижущих сил.
