О природе кальцийсодержащего уранинита

А.А. Вальтер, А.И. Писанский

Abstract
The investigation of calcium-bearing uraninite from ores of the Severinskoe deposit of albitite-uranium formation of the central part of the Ukrainian shield is performed. On the electron microscopy level of investigation, the mineral is homogeneous and has the stoichiometric atomic ratio, Ca : U = 1 : 2. The powder diffraction pattern is the same as that for uraninite with a₀ = 0.537(±0.001)nm. The identity of the mineral with artificial compound CaU₂O₆ with the fluorite-type structure is assumed.
