The glass-formig concentration region of the calcium nitrate-potassium nitrate-water system was determined. The glass transition temperature can be in the studied region approximated by a linear function of the salt concentrations. A comparison of the properties of the studied system with the hydrated calcium nitrate and chloride mixture revealed important differences in the effect of different salts on the undercoolability of aqueous calcium nitrate solutions.
