摘要：

Heat capacities of monoclinic selenium have been measured by computer interfaced differential scanning calorimetry from 100 to 379 K. Using literature data for low temperature heat capacities, enthalpies, entropies, and free enthalpies are calculated up to the zero entropy production melting temperature of 413 K. A comparison with trigonal selenium shows that there is no floor temperature for the stability of trigonal selenium. Monoclinic selenium is metastable relative to trigonal selenium at all temperatures. © 1979.
