dc.description.abstractIn this research novel microcomposites composed of phase change materials (PCMs) and xonotlite were fabricated and characterized. Xonotlite mineral and its composites have wide application areas in building materials industry due to their thermo-insulating properties. Lauric acid, decanoic acid and paraffin were used as phase change materials. Xonotlite was prepared as composite matrix. In order to analyse the composite structure and thermal performance of microcomposites, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used. The experimental results demonstrate that paraffin/xonotlite composites were synthesized successfully and paraffin was the most suitable phase change material for preparation of phase change material/xonotlite composites. However, this study emphasized the correct choice of PCM that will be used in xonotlite including composites. Fatty acids have dissolution effect on xonotlite matrix. The melting and freezing temperatures were measured through differential scanning calorimetry analysis and found to be 35.05 and 40.42 degrees C, respectively. The melting and crystallization heats were determined to be 65.8 and -63.5 kJ/kg. We recommended that the fabricated nanocomposite-PCMs offer proper phase transition temperature range heat enthalpy values for thermal energy storage applications.
