ABSTRACT:
A mixture for the storage of heat energy utilizing a heat of fusion material includes sodium sulfate decahydrate, borax as a nucleating agent, and hydrous magnesium aluminum silicate (attapulgus clay) as a homogenizing agent. This composition maintains the salt-hydrate in suspension during repeated heating and cooling cycles.
A method is also disclosed for preparing the mixture which includes the steps of mixing water with the attapulgus clay, adding a nucleating agent to the initial mixture, and mixing the initial mixture, including the nucleating agent, with a heat of fusion material such as sodium sulfate decahydrate.
