赤铁矿

"Subsequent analysis of the flask material and dust has shown that the magnetite was transformed into the red mineral hematite, through a completely mechanical process without the presence of water at any stage of this process," said Merrison, who presented the work yesterday at the European Planetary Science Congress in Germany.

&随后对于烧瓶内的材料和粉尘的分析表明，磁铁矿通过一个在过程中的任何阶段都没有水存在的完全的机械过程，变成了红色的矿物赤铁矿，&麦里逊说。他昨天在德国召开的欧洲行星科学大会上对这项工作做了介绍。

ABSTRACT Iron carbide is a promising new material for steelmaking in the future.

碳化铁是一种很有前途的新型炼钢原料，为了解碳化铁制备过程中的有关规律，在实验室中进行了赤铁矿粉、磁铁矿球团制备碳化铁的基础研究。

It is shown that the main minerals in the slag are quartz, gypsum, mullite and hematite; an obvious characteristic apex of gypsum appears in the DSC curve when dehydrating but the apex is low total amount of SiO2, SO3, Al2O3, CaO and Fe2O3 is above 80%; there are several kinds of sulphates, not only calcium sulphate but also other sulphates with high solubility.

结果表明，电解锰渣中的主要结晶矿物为石英、二水石膏、莫来石及赤铁矿，电解锰渣有比较明显的石膏受热脱水峰，但峰值小；电解锰渣中SiO2、SO3、Al2O3、CaO和Fe2O3的总量占80%以上；电解锰渣中硫酸盐有二水石膏，也有含量较高的大溶解度硫酸盐。

The obvious differences of colors and components exist between the oolith lamellar shells composed of hematite and those composed of kaolinite.

鲕粒同心纹层由赤铁矿及高岭石组成，存在着明显的颜色、成分差别。

Both magnetite and iron/maghaemite core/shell nanoparticles were superparamagnetic at room temperature with a blocking temperature at 80 K and 67 K, respectively.

在室温下，磁铁矿和铁/磁赤铁矿核/壳纳米颗粒都是超顺磁性的，其阻隔温度分别为80K和67K

On the other hand, the higher contents of hematite would not necessarily make the rocks red-colored, due to the suppression by other pigments, such as organic matter in black or ferrous iron of chlorite in green.

总体而言，浅红色岩层含有最高的总铁含量和赤铁矿铁，灰色岩层则以顺磁性的亚铁为主，暗色和绿色岩石仅含有顺磁性的二价铁或者与相对丰度较低的三价铁共存。
