科学家们揭示了一种新形态的水,即在温度达到 5000℃时,冰也不会融化。这是因为在这样的条件下,水分子被固定在固态的立方形晶格中,而氢原子则可以自由活动。正是这种晶体结构,让超离子冰具有更高的导电性,在将近 5000℃的条件下仍不融化。

研究人员在实验室中制造了第一块超离子冰,证实了其在存在晶体结构。最近,斯坦福大学的物理学家发现了超离子冰的一种新形态。科学家们通过实验发现,冰 18 与冰 17 具有不同的晶体结构,确定了冰 18 是超离子冰的一种新的形态。此外,冰 18 相比于冰 17,还有更高的导电性。

研究人员指出,冰 18 可能有助于解释“旅行者”2 号在飞越太阳系的两颗冰巨星——天王星和海王星时,发现的异常磁场。天王星和海王星的磁场都不同寻常,它们都发生了倾斜和扭转。科学家们提出了多种解释,但始终未能弄清楚这种磁场异常的现象。根据法拉第电磁感应定律,变化的电场产生磁场。有科学家认为,海王星内部的液态物质和超离子冰的导电性差异可能是导致磁场异常的原因之一。
