High Purity SphereAmerican 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 Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. American Elements specializes in producing Thorium as ribbon in various thicknesses and sizes. Most ribbon is rolled for use in coating and thin film Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Thicknesses up to 0.02" and widths up to 1" are available for most metals. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation. American Elements specializes in producing custom compositions for commercial and research applications and for new proprietary technologies. American Elements also casts any of the rare earth metals and most other advanced materials into rod, bar, or plate form, as well as other machined shapes and through other processes such as nanoparticles () and in the form of solutions and organometallics. We also produce Thorium as rods, powder and plates. Other shapes are available by request.

Thorium (Th) atomic and molecular weight, atomic number and elemental symbol Thorium (atomic symbol: Th, atomic number: 90) is a Block F, Group 3, Period 7 element with an atomic weight of 232.03806. The number of electrons in each of thorium's shells is [2, 8, 18, 32, 18, 10, 2] and its electron configuration is [Rn] 6d2 7s2. Thorium Bohr ModelThe thorium atom has a radius of 179 pm and a Van der Waals radius of 237 pm. Thorium was first discovered by Jöns Jakob Berzelius in 1829. The name Thorium originates from the Scandinavian god Thor, the Norse god of war and thunder.Elemental Thorium In its elemental form, thorium has a silvery, sometimes black-tarnished, appearance. It is found in small amounts in most rocks and soils. Thorium is a radioactive element that is currently the best contender for replacing uranium as nuclear fuel for nuclear reactors. It provides greater safety benefits, an absence of non-fertile isotopes, and it is both more available and abundant in the Earth's crust than uranium.
