Scheelite CaWO

The X-ray crystal structure of K[RuO ] shows the salt to have the scheelite (CaWO ) structure with a slightly flattened tetrahedral anion (mean Ru=(0) 1.79 A) [451], A single crystal X-ray structure of TRAP shows this to contain the expected tetrahedral anion [472],... [Pg.32]

The principal ores of wolfram are scheelite, CaWO, and toolf-ramite, (FeMn) VO, ... [Pg.524]

Molybdenum and its uses. Molybdenite, molybdenum trioxide, ammonium molybdate. Wolfram (tungsten) and its uses. Scheelite, CaWO, and wolframite, (Fe,Mn)W04. Wolfram carbide. Uranium and its ores pitchblende, car-notite. Sodium diuranate, uranyl nitrate. Nuclear fission. [Pg.529]

Extraction reactions. Valuable components such as metals could be extracted from compounds or minerals under hydrothermal or solvothermal conditions. For example, potassium and tungsten components could be extracted from mother liquids of potassium minerals and tungsten minerals (Scheelite, CaWO/)), respectively, under hydrothermal conditions. [Pg.119]

The scheelite structure-type Is commonly adopted by compounds with the stoichiometry ABO, when the A cation Is fairly large (>1.0 A) and the B cation fairly small (on the order of 0.6 A). The prototype of this structure Is the mineral scheelite, CaWO, which crystalllzes( ) with four formula units... [Pg.61]

Scheelite, CaWO, is present in epigenetic rocks, volcanic and sedimentary, formed in processes near the surface of the earth. In the ores the scheelite content is as a rule low, corresponding to, for example, 0.5% WOj. The finding and identification of such small quantities is helped by the fact that scheelite fluoresces with a bluish-white light in UV radiation, (Figures M38 and M39). The scheelite mineral has a certain... [Pg.615]

M39 Scheelite CaWO in UV-radiation. The scheelite fluoresces in the UV-light with a white color, quite different from the surrounding minerals. [Pg.1298]
