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

Phase equilibria in sections of the calcium-nitrate–glycerol–water system at temperatures from 0 to –47°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.
