Abstract

L'invention concerne un milieu de stockage de chaleur. Le milieu est constitué par le mélange d'une composition de matière à base d'un sel polyhydraté, tel que sulfate de sodium hexahydraté, carbonate de sodium décahydraté, chlorure de calcium décahydraté avec un agent nucléant et d'une boue colloïdale d'argile thixotropique, telle qu'attapulgite ou bentonite peptisée. Le % de dégradation est abaissé à quelques % pour 200 cycles et plus. L'invention s'applique au stockage thermique de l'énergie solaire.
