| Abstract: | A new supported phase change material (PCM) made of molten salts impregnated by capillary forces in a porous-nickel matrix is presented. The preparation of molten salts/porous-nickel matrix PCMs was mainly discussed. Structures and properties of these materials were studied by X-ray diffraction (XRD) analysis, scanning electronic microscopy (SEM) observation and differential scanning calorimetry (DSC) analysis. The optimum composite time was 2～3 hours. The optimum composite temperature was 50～100 ℃ above melting point of the molten salt. Heat storage density of PCMs was also discussed. |
