Phase Equilibria in Sections of the Calcium-Nitrate-Glycerol-Water System at Temperatures from 0 to-47 degrees C

Phase equilibria in sections of the calcium-nitrate-glycerol-water system at temperatures from 0 to -47 degrees C are studied by visual polythermal analysis. The ratio of calcium nitrate and glycerol in the sections varies from 3 : 1 to 1 : 3. It is found that all nitrate-glycerol compositions are characterized by good ice-melting capacity and form low-temperature eutectics. These compositions are promising for the development of new anti-icing agents on their basis.
