Abstract
The invention relates to salt mixtures composed of Mg(NO.sub.3).sub.2.6H.sub.2 O and LiNO.sub.3 in a mass ratio of 86-81:14-19 for storing and utilizing thermal energy in the form of heat of phase transformation. They are eminently suitable as latent heat storage media for heat reservoirs for storing and utilizing the waste heat of motor vehicle engines.
