Abstract: The way in which strontium chloride hexahydrate prevents the supercooling of latent heat storage systems based on calcium chloride hexahydrate was investigated. It can be established from the ternary equilibrium system CaCl2---SrCl2---H2O and proved also experimentally that crystals of strontium chloride hexahydrate separated from one another are unsuitable for the prevention of the supercooling of calcium chloride hexahydrate melts, because of the dehydrating properties of the melt. Cohering agglomerates (of 2-3 cm) of microcrystals, containing adhering water, preserve for a much longer time their nucleating property, because concentration conditions established in the interior of the aggregation differ from the composition needed for the melt. The life of the nucleating agent depends on the length of time for which this concentration gradient is equalized by diffusion processes.
