Abstract
The phase composition of the product of thermal dehydration of a mixture of crystallohydrates of magnesium and calcium nitrates with a bulk composition Mg(NO3)2 · Ca(NO3)2 ⋅ 2.7H2O is determined via X-ray phase analysis and its IR spectrum is obtained. It is found that the sample solidifies upon cooling to form a compact nonhygroscopic mass. A sample with a higher concentration of water is hygroscopic and deliquescent in air. Deeper dehydration is accompanied by hydrolysis with the formation of basic salts. The anti-icing properties of the dehydrated nitrate sample are determined.
