About Tungsten

Tungsten is a transition metal with atomic number 74 and the highest melting point of any metal. Tungsten carbide is used in cutting tools and wear resistant components, while tungsten oxides and tungstates provide additional electronic and optical functions. Europium(III) tungstate is studied for its luminescence and energy transfer behavior, connecting tungsten chemistry to the development of phosphors and other light emitting materials.
