Use: Calcium Fluoride is a water insoluble Calcium source for use in oxygen-sensitive applications, such as metal production. Fluoride compounds have diverse applications in current technologies and science, from oil refining and etching to synthetic organic chemistry and the manufacture of pharmaceuticals. Magnesium Fluoride, for example, was used by researchers at the Max Planck Institute for Quantum Optics in 2013 to create a novel mid-infrared optical frequency comb composed of crystalline microresonators, a development that may lead to future advances in molecular spectroscopy. Fluorides are also commonly used to alloy metals and for optical deposition. Calcium Fluoride is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia)and follows applicable ASTM testing standards.
