  • Scheelite - The Fluorescent Tungsten Ore

    Crystal StructurePhysical PropertiesOriginApplicationsOccurrenceScheelite is a calcium tungstate mineral that is the dominant member of a solid solution series between tungsten-rich scheelite (CaWO4) and rare molybdenum-rich powellite (CaMoO4), a much less common variant. This solid solution explains why most scheelites contain certain amount of molybdenum in their structure. Scheelite crystallizes in the tetragonal system, often forming as tetragonal dipyramids which look like octahedrons. Additionally, it may be tabular, massive, granular or columnar, sometimes as grai
  • Scheelite - Wikipedia

    Scheelite is a calcium tungstate mineral with the chemical formula Ca W O 4.It is an important ore of tungsten (wolfram). Well-formed crystals are sought by collectors and are occasionally fashioned into gemstones when suitably free of flaws. Scheelite has been synthesized using the Czochralski process; the material produced may be used to imitate diamond, as a scintillator, or as a solid ...
