Abstract

Abstract: In this paper, a novel form-stable phase change material (PCM) for high-temperature thermal energy storage was prepared and characterized to overcome the leakage and incompatibility issue of PCM. Al was used as PCM and Al2 O3 as skeleton material. An improved mixed sintering method was employed for preparation, and thermophysical properties such as melting point, latent heat and thermal conductivity were measured to evaluate the performance of the form-stable PCM. The results showed that the optimum molding condition was 400 MPa for 5 min to obtain a have good compactness and stability. The maximum mass fraction of Al without leakage was 60%, and the peak values of latent heat and thermal conductivity of the composite was 194.2 J/g and 2.15 W/m·K, respectively.
