Low-temperature heat capacity of a two-dimensionally ordered structure of ice crystallized from glycerol aqueous solutions
2010 (English)In: Thermochimica Acta, ISSN 0040-6031, E-ISSN 1872-762X, Vol. 500, no 1-2, 106-110 p.Article in journal (Refereed) Published
A two-dimensionally ordered structure of ice crystallized from a glycerol 55% (w/w) aqueous matrix has been studied by adiabatic calorimetry. Its heat capacity was measured between T = 5 K and T = 15 K and found to be consistently larger than that of hexagonal ice (ice Ih) by an average of 1.3%. The composition and the heat capacity of the maximally freeze-concentrated solution, i.e. the non-crystallizing glycerol-rich phase that remains after water's partial crystallization, were also investigated.
