Compact thermal energy storage for solar applications requires new phase change materials with higher thermal energy storage capacities. In this study, nano magnetite (Fe2O3) particles were prepared with the sol-gel method to be used for enhancing thermal properties of paraffin. 10% nano particle was added to paraffin (melting range: 56-58 degrees C and latent heat: 119 J/kg) to prepare a nano composite. SEM analysis shows that nano magnetites are homogeneously distributed in paraffin structure with particle size in the range of 15-25 mu m. Latent heat of the paraffin nano composite measured by DSC was 144 J/g. This result indicated that thermal storage capacity of paraffin can be increased by about 20% by addition of 10% nano magnetite. Further analysis on determining thermal conductivity and thermal stability is ongoing. (C) 2012 The Authors. Published by Elsevier Ltd.
