The effective thermal conductivity was investigated for lanthanum sulfate hydrate/expanded graphite (La2(SO4)3・xH2O/EG) heat storage material. Moreover, reactivity of La2(SO4)3・xH2O was also investigated. The hydration number strongly depended on the atmosphere condition. The effective thermal conductivity of La2(SO4)3・xH2O/EG decreased with increasing content of La2(SO4)3・xH2O, and the effective thermal conductivity measured at around 33°C was slightly higher than that measured at around 116°C. Moreover, the effective thermal conductivity of La2(SO4)3/EG was lower than that of La2(SO4)3・xH2O/EG at around 33°C. Furthermore, the chronological changes of hydration reactivity of La2(SO4)3・H2O was measured at 80°C.
