摘要

采用热重分析、差示扫描量热法和核磁共振等方法研究了kmgcl3·6h2o的热力学性质和结构几何形状。初始质量损失发生在351 K (=T d)左右,这被解释为部分热分解的开始。相变温度分别为435 K (=T C1)和481 K (=T C2)。氢原子核的自旋-晶格弛豫时间t1的温度依赖性在t1附近突然改变。这些变化与八面体水分子排列的几何变化有关。

Thermodynamic properties and structural geometry of KMgCl 3 ·6H 2 O single crystals
The thermodynamic properties and structural geometry of KMgCl 3 ·6H 2 O were investigated using thermogravimetric analysis, differential scanning calorimetry, and nuclear magnetic resonance. The initial mass loss occurs around 351 K (=T d ), which is interpreted as the onset of partial thermal decomposition. Phase transition temperatures were found at 435 K (=T C1 ) and 481 K (=T C2 ). The temperature dependences of the spin–lattice relaxation time T 1 for the 1 H nucleus changes abruptly near T C1 . These changes are associated with changes in the geometry of the arrangement of octahedral water molecules.
