英文摘要 | the heat capacities of linh2 and li2mgn2h2 were measured by a modulated differential scanning calorimetry (mdsc) over the temperature range from 223 to 473 k for the first time. the value of heat capacity of linh2 is bigger than that of li2mgn2h2 from 223 to 473 k. the thermodynamic parameters such as enthalpy (h-h (298.15)) and entropy (s-s (298.15)) versus 298.15 k were calculated based on the above heat capacities. the thermal stabilities of them were investigated by thermogravimetric analysis (tg) at a heating rate of 10 k min(-1) with ar gas flow rate of 30 ml min(-1) from room temperature to 1,080 k. tg curves showed that the thermal decomposition of them occurred in two stages. the order of thermal stability of them is: li2mgn2h2 > linh2. the results indicate that addition of mg increases the thermal stability of li-n-h system and decrease the value of heat capacities of li-n-h system. |
