Abstract: We developed a core-shell type microencapsulated phase change material (MEPCM) which has high storage density for high temperature (> 500 ℃) applications. Al-Si alloy with melting temperature of 577 ℃ was selected as a PCM. The MEPCM was prepared in two steps: (1) the formation of an AlOOH shell on the PCM particles using a boehmite treatment, and (2) heat-oxidation treatment in an O_2 atmosphere to form a stable α-Al_2O_3 shell. As results, the MEPCM covered with dense α-Al_2O_3 shells were successfully prepared and it presented a melting point of 573 ℃, latent heat of 247 J g^<-1>, and good cyclic performance. These results indicated the possibility of using MEPCM at high temperatures. The MEPCM developed in this study has great promise in future energy and chemical processes, such as exergy recuperation and process intensification.
