Structure and thermal expansion of a new polymorph of pentahydrite (MgSO4·5H2O)

In our high-pressure studies of candidate outer solar system minerals using PEARL, we have found that MgSO4.7H2O (epsomite) decomposes to a lower hydrate mixed with water ice....我们采用PEARL设备开展外太阳系候选矿物的高压实验研究，实验过程中发现七水硫酸镁（MgSO₄·7H₂O，泻利盐（epsomite））会分解为低水合硫酸镁与水冰的混合物。
