“…4 shows the temperature dependence for specific heat and thermal conductivity obtained by Wang et al [85] at different cycles. The compatibility and corrosion problems of Al-Si alloys in high-temperature applications have been studied with graphite-carbon encapsulation material [73], ceramic encapsulation material [64,86], Al2O3 shell encapsulation [87], honeycomb ceramic encapsulation [88], ceramic coated stainless-steel [89], Al2O3@Cu multilayer shell [90]. Recently, Li et al [91] investigated a microstructured metal-based composite that consists of aluminium as PCM and alumina as a skeleton structural supporting material as a solution for the leakage of corrodible liquid PCMs.…”

“…13) Dindi et al investigated the corrosive behavior of between Al-Sibased PCM and BN coated stainless steel, and reported that no reaction occurred between them even after 720 melting and solidification cycles. 14) Furthermore, encapsulation of PCMs is being considered to improve the corrosion resistance. Zhang et al coated the surface of millimeter-sized Cu PCMs with Cr-Ni, which showed no leakage of Cu after more than 1 000 melting and solidification cycles.…”

To achieve high energy efficiency and CO 2 reduction during iron-and steelmaking, thermal management is vital. Use of phase change material (PCMs) to store excess energy in the form of latent heat has the potential to realize excellent thermal management. Microencapsulated PCMs (MEPCMs) consisting of an alloy PCM core and an oxide coating have improved corrosion resistance and are easy to mix with other materials. Conventionally, composite PCM pellets are fabricated by mixing glass frit (to aid sintering) with Al-25 mass% Si MEPCM. However, this process has not yet been optimized. In this study, the optimal stoichiometry of composite PCMs prepared using Al-25 mass% Si MEPCM and glass frit was investigated. The pellets were prepared by mixing with glass frit at 60, 80 and 90 mass% of MEPCM, followed by molding and heat treatment. As a result, pellets were successfully fabricated with condition including 60 and 80 mass% of MEPCM. The latent heat capacity of the composite PCM was 146 J g -1 , which was at least 1.59 times higher than that of existing sensible heat storage (SHS) materials. Moreover, the composite PCMs withstood 300 melting and solidification cycles. In summary, composite PCMs with excellent latent heat capacity and durability were successfully prepared. KEY WORDS: latent heat storage; phase change material; thermal energy storage; composite material; microcapsule.

“…[7][8][9][10][11][12][13] To introduce the metals/alloys PCM into the system, measures are needed that help prevent corrosion reactions with structural materials such as the heat storage tank and heat exchanger due to their high corrosivity during melting. 14 Dindi et al 15 investigated the effect of the reactivity between a stainless steel vessel and an Al-Si alloy PCM (melting point: 577 C) and reported the formation of intermetallic phases of $300 μm sizes after 50 melting/ solidification cycles of the PCM. In addition, corrosion resistance was found to improve upon coating the surface of the stainless-steel vessel with BN.…”

Latent heat storage (LHS) using phase change materials (PCMs) is expected for application to heat utilization at high‐temperature because it can provide a heat source of high density and constant temperature. Even among PCMs, metals/alloys are promising for high‐temperature operation. However, metals and alloys PCM are concerned about corrosion reactions with structural materials. As a result, micro‐encapsulated PCMs (MEPCMs) have been created in which the surface of alloy PCM is encased in a stable oxide coating. Since the surface of MEPCM is an oxide, the creation of structures with the function of LHS in a variety of shapes by combining MEPCM with sintering aids is also possible. In this study, composite PCMs were prepared by combining Al‐25 mass% Si MEPCM with fine α‐Al2O3 particles as a sintering aid. Consequently, PCM composites containing 70‐90 vol.% of the MEPCM and heat‐treated at 1200°C or 1300°C were successfully fabricated. In particular, a high heat storage density of 0.47 GJ m−3 was obtained under conditions containing 90 vol.% of the MEPCM and a heat treatment temperature of 1200°C, which is 1.6‐fold higher than that of existing sensible heat storage materials. Additionally, the composite PCM retained its shape and the latent heat capacity even after 300 cycles of cyclic testing. Thus, the high heat storage density and high durability of the composite PCM are expected to further promote the expansion of high‐temperature heat utilization in future studies.
