Abstract: Temperature dependency of densities of the liquid system magnesium nitrate hexahydrate — zinc nitrate hexahydrate was measured. Densities of liquid mixtures were experimentally measured at different temperatures by a method using submersible corpuscle. Based on the obtained data, temperature dependence on the density was obtained. A model describing the density in the whole concentration range very well was created.

Keywords: phase change materials, density, density of liquids, zinc nitrate, magnesium nitrate
