Abstract

The preparation and characterization of composites of MgSO4•7H2O compounded with KAl(SO4)2•12H2O for thermal storage are reported in the present article. The co-melting method is employed to conduct the preparation. The thermal properties of the composites are studied. The results show that: the phenomenon of phase separation disappears in the composite system in all the tested samples, and the optimized mass ratio is about 5: 5, which results in the lowest phase change temperature, longest heat releasing platform and highest latent heat; the enthalpy is still 716.05kJ / kg after 50 thermal cycles. Thus, this composite material has the great potential to be used as phase change thermal storage material for low temperature.
