| Abstract: | DSC method was used to study binary mixtures pentaglycerine (PG) and tris (hydroxymethyl)amnomethane (TAM) of phase transitions for thermal energy storage.,which were include transitions temperature and transitions enthalpies. Step-cooling curve method was used to study the relation between transitions phase and time,then prove that the solid-solid phase transitions were accord with the Arrhenius equation and determine the reaction order of phase transitions and activation energy. |
