单词 schoepite
释义 schoepite Min.|ˈsxɜːpaɪt|
[f. the name of Alfred Schoep (1881–1966), Belgian mineralogist + -ite1.]
A hydrated form of uranium trioxide found as yellow to brown tabular or prismatic orthorhombic crystals as an alteration product of uranium ore; three phases (schoepite I, II, and III) are known, differing slightly in composition, colour, and morphology.
1923T. L. Walker in Amer. Mineralogist VIII. 69 As this mineral appears to be quite distinct in optical and crystallographic properties from all known uranium minerals, the writer proposes to name it schoepite in honor of Professor Alfred Schoep, of the University of Ghent, who has contributed so much to our knowledge of the secondary uranium minerals from the Congo.1960Ibid. XLV. 1034 Crystals of schoepite that are apparently single yield multiple diffraction patterns... These..correspond to the presence of two out of three possible distinct orthorhombic phases in parallel intergrowth in the crystal. The three phases are designated schoepite I, II and III.1965Ibid. L. 236 Crystals of schoepite commonly occur with an amber-brown core completely or partially surrounded by a derivative golden-yellow rim which retains the morphology of the original crystal... The brown part consists chiefly of schoepite I, and the yellow part mostly of schoepite II or schoepite III.
