Abstract: The authors created a series of composite latent storage materials (CLSM) using expanded graphite (EG) and a two different metal nitrate phase change materials (K and Li, K and Na). The steady-state comparative method was used in order to measure thermal conductivities because it was deemed the best technique. Properties investigated that were related to the effective thermal conductivity were material temperature and microstructure and their effect on thermal conductivity.
