Abstract

The preparation and characterization of anti - blocked composite material consisting of MgSO4·7H2O and KAl(SO4)2·12H2O for thermal energy storage are reported in the present article. The preparation is performed by co-melting method by adding CaCO3 as the anti-blocking agent. The thermal properties of the composite are studied. The results show that: the phenomenon of phase separation disappears in the composite system during all the tested procedure for sample with the mass ratio of 9: 1; the enthalpy is about 800kJ / kg after 60 heating-cooling cycles; the solidifying temperature of this anti-blocked composite keeps almost unchanged. Thus, this composite material has the potential to be used as low temperature phase change thermal storage material.
