Mirabilite, commonly known as Glauber’s salt, is a typical inorganic hydrated salt used as phase change material. Its natural abundance, high latent heat and convenient phase change temperature (32℃) make it an attractive material for storing low grade solar heat and building heating applications .
Low, medium-low, medium, and high temperature applications. An upcoming focus should be life cycle analyses of biobased phase change materials. Harnessing the potential of phase change materials can revolutionise thermal energy storage, addressing the discrepancy between energy generation and consumption.
The latent heats of melting and crystallization of CGCA-supported mirabilite phase change materials (CGCA-PCMs) are 157.1 and 114.8 J·g −1, respectively. Furthermore, after 1500 solid—liquid cycles, there is no leakage, and the retention rate of crystallization latent heat is 45.32%, exhibiting remarkable thermal cycling stability.
Organic phase change materials (PCMs) have been widely used in the thermal energy storage field, but melt leakage above the phase change temperature has greatly hindered their practical applications.
In particular, latent heat storage through phase change materials has attracted extensive attention for its large storage capacity , . Phase change materials (PCM‘s) are effective latent heat thermal storage materials because they store and release thermal energy during the process of melting and freezing .
