钓鱼岛石是钓鱼岛附近海洋沉积物中发现的一种新矿物。我们测定了不同铬含量的钓鱼岛石系列的晶体结构,它们是由双尖晶石单元组成的层状结构,层间由一个含有钠离子的结构层隔开,氧原子按照立方密堆积的ABCA方式堆积。这些钓鱼岛石的六方晶格常数与其中铬的含量线性相关。本文还讨论了钓鱼岛石中铝离子被铬离子取代的情况。
Diaoyu Islands stone is a new mineral found in marine sediments near the Diaoyu Islands. We measured the crystal structure of the Diaoyu Islands series with different chromium contents. They are layered structures consisting of double spinel units separated by a structural layer containing sodium ions. The oxygen atoms are arranged in a cubic and close packed ABCA mode accumulation. The hexagonal lattice constants of these Diaoyu Islands are linearly related to the chromium content. This paper also discusses the replacement of aluminum ions in the Diaoyu Islands with chromium ions.
