晶质铀矿和沥青铀矿是铀的简单氧化物中的两个最重要的矿物,其化学分析所提供的主要化学组份是UO_2和UO_3。矿物的晶体化学研究结果表明,晶质铀矿和沥青铀矿具有相同的晶体结构——CaF_2型,属于同一矿物种。所以,有些国家的矿物学家将二者统称为“Ura-ninite”。但是,晶质铀矿和沥青铀矿在晶体形态及某些物理性质方面是有差别的,矿物成因及产出的地质条件也不尽相同,就是在晶体结构方面也有差别:晶质铀矿晶胞中的 Crystalline and uraninite are the two most important minerals in simple oxides of uranium. The main chemical components provided by chemical analysis are UO 2 and UO 3. Crystallographic chemistry results show that crystalline uraninite and uraninite have the same crystal structure - CaF 2 type, belonging to the same mineral species. Therefore, some countries mineralologists will both referred to as “Ura-ninite”. However, crystalline uranium ore and pitch uranium ore are different in crystal morphology and some physical properties. The geological conditions of the genesis and output of minerals are also different, that is, there are also differences in crystal structure: crystalline uranium crystal In the cell
