ABSTRACT:
A thermal energy storage composition is disclosed that stores heat upon melting and releases heat upon solidification. It is composed of a mixture of sodium sulfate decahydrate, sodium carbonate decahydrate, sodium borate decahydrate and a thickening agent. Its good heat transfer characteristics, relatively high latent heat of fusion, low cost, and favorable melting point allow this material to be particularly useful for space heating applications.
