Abstract
Based on a study of the phase equilibria in cuts of a Mg(NO3)2–Ca(NO3)2–H2O system at temperatures of 0 to–50°C, new deicers have been developed, including a liquid solution of magnesium and calcium nitrates and a solid composition of dehydrated nitrates. The ice-melting capacity of the agents under equilibrium conditions was determined. It was established that agents made of dehydrated magnesium and calcium nitrates interact with ice via heat release, which accelerates ice melting. The corrosion activity of liquid of a nitrate agent toward metals (in the collaboration with the All-Russian Institute of Aviation Materials) was determined. It was established that it can be significantly decreased at the introduction of a corrosion inhibitor. The possibility of synthesizing agents from natural mineral raw materials (dolomite, magnesite, and calcite) has been considered.
