Abstract

Abstract:

Shaped composite phase change materials (SCPCMs) have the advantages of high energy storage density and high thermal stability. However, the internal phase change medium in the molten state is prone to leakage as it continuously absorbs heat during phase changes, resulting in material deformation and corrosion. To overcome this, a high temperature-shaped composite phase change material (HTSCPCM) was prepared using sodium hydroxide-modified fly ash (mFA) as a ceramic matrix and Al-12Si alloy powder as a phase change medium using a hybrid sintering method. Testing and characterization were conducted using scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction, fully automated specific surface and porosity analyses, thermogravimetry-differential scanning calorimetry, and thermal conductivity. The results showed that sodium hydroxide-modification of FA resulted in multilevel surfaces and enhanced specific surface area (3.82 to 40.86 cm²/g) and pore volume (0.008 to 0.085 cm³/g). The Al-12Si alloy was shown to be securely bonded to the mFA ceramic matrix. The maximum loading of the matrix to the Al-12Si alloy was 65%, the latent heat of phase transition was 97.76 J/g, and the thermal conductivity was 15.10 W/(m·K). After 100 thermal cycles, the morphology of the AI-12Si/mFA HTSCPCM was unchanged, and no leakage was observed. The latent heat of the phase change was 91.32 J/g, and it decreased by only 6.6% before and after each cycle. The AI-12Si/mFA HTSCPCM prepared in this work has the advantages of a suitable phase transition temperature, high thermal conductivity, high heat storage density, and ease of processing. The results of this study indicate that this AI-12Si/mFA HTSCPCM can be used in the field of high-temperature heat storage.
