“…This is a typical MGA microstructure with a high volume fraction of discrete PCM (Al) particles, well separated by the matrix phase (MgO) as seen in previous work [12,13,16]. No evidence for microstructural degradation was found.…”

“…Samples were fired in batches of three identical pellets using an inert atmosphere (Ar flow) at a temperature of 700 °C in a horizontal tube furnace. This temperature was chosen for compatibility with previous C-Al experiments [16] and to avoid the viscosity of the melted Al particles becoming too low which it was felt may cause some leakage in the early stages of firing. This treatment is insufficient to cause full sintering of the pure ceramics which generally requires heating in the range 1200-1800 °C.…”

The performance of the material is determined by its structure, i.e., the composition of the material elements of the atomic structure, the molecular structure, and atoms or molecules in space arrangement and the aggregation characteristics. The microstructure of the material has important implications for the material performance. In this paper, five phase change materials, potassium nitrate, sodium nitrate, and the composites of KNO3-NaNO3/graphite (3%, 6%, and 9%), have been studied by the experiment, and the aim is to improve the storage performance of the solar storage system. The results show that potassium nitrate and sodium nitrate are significantly different in microstructure, that is, potassium nitrate is a layered structure and the sodium nitrate is a network structure. And, the graphite as additives can be physically combined with the molten salts, which leads to a different performance and distribution in the mixture. Therefore, it is an effective method in improving the performance of molten salts by using graphite as the supporting material. The results can provide a reference to future choose for solar storage materials.

Among metal‐based phase change materials (PCMs), Al and its alloys have garnered significant attention due to their high latent heat and high thermal conductivity. However, challenges such as leakage, corrosion, and oxidation have limited their widespread application. Numerous researches have demonstrated that encapsulating Al and its alloy PCMs is one effective way to address these problems. This review provides a comprehensive overview of the characteristics, encapsulation strategies, and applications of Al and its alloy PCMs. First, the advantages and thermal properties of Al and its alloy PCMs are introduced, and their problems are then discussed. Subsequently, various encapsulation strategies that are expected to solve the above problems are summarized and compared. Additionally, the applications of Al and its alloy PCMs in solar thermal energy storage, catalysis, and electric vehicles are reviewed. Finally, current challenges, potential solutions, and the key direct of future study are presented.
