説明

This study reports 1) their corrosion effects to ceramic materials, 2) thermal analysis of Al-Si alloys as candidates of high-temperature (over 500℃) phase change material (PCM), and 3) new encapsulation technique for the PCM. Four Al-Si alloys were selected as the PCM. Engineering ceramics such as Al_2O_3, AlN, Si_3N_4, SiC, and SiO_2 were used for corrosion tests. The corrosion tests revealed that Al_2O_3, AlN, and Si_3N_4 shows high corrosion resistance to molten Al-Si alloys, therefore, they were suitable as structural materials for latent heat storage systems (LHS) using Al-Si alloys. Results of thermal analysis shows the ADC12 and Al-25wt%Si were promising PCM due to their large latent heat. Mushroom-like Al_2O_3 capsules were applied to the new encapsulation technique. In addition, the prepared PCM capsule showed good durability. These results indicated the feasibility of a high temperature LHS using Al-Si alloys and ceramics.
