Heat storage mass of salts

摘要

Salts undergo one or more polymorphic transformations in a given temp range. The crystals of the mass are marked by included crystals which are isomorphic, isotypical or epitaxial with the low-temp form of the including crystals. The included crystals undergo no transformation in the temp range. Pref. thermal conductivity, is increased by adding Al particles before or after incorporation of the included crystals. A reinforcement of BaCO3 may be added. Used for power economy.
