Abstract
A phase change material for use in a heat battery is provided which includes a salt of hydrated Group IIA metal nitrate and Group IA metal nitrate and an effective amount of an aqueous material sufficient to cause the densities of the liquid and solid phases of said phase change material to be approximately equal during phase transformation. A method of making the phase change material and a heat battery which contains the phase change material are also provided.
