American Elements specializes in producing high purity uniform shaped Thorium Wire with the highest possible density High Purity Metal Wire Image for use in semiconductor, 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), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard Metal Wire sizes range from 0.75 mm to 1 mm to 2 mm diameter with strict tolerances (See ASTM requirements) and alpha values (conductive resistance) for uses such as gas detection and thermometry tolerances (Also see Nanoparticles) . Please contact us to fabricate custom wire alloys and gauge sizes. 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 can also provide Rod outside this range. See research below. We also produce Lead as powder, ingot, pieces, pellets, disc, granules and in compound forms, such as oxide. Other shapes are available by request.

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. The 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. 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.

Free Test Sample Program

We recognize many of our customers are purchasing small quantities directly online as trial samples in anticipation of placing a larger future order or multiple orders as a raw material for production. Since our primary business is the production of industrial quantities and/or highly consistent batches which can be used for commercial production and purchased repeatedly in smaller quantity, American Elements offers trial samples at no charge on the following basis. Within 6 months of purchasing materials directly online from us, you have the option to refer back to that order and advise that it is the intention of your company, institution or lab to either purchase a larger quantity, purchase the material in regular intervals or purchase more on some other basis.

We will then evaluate your future needs and assuming the quantity or number of future purchases qualify, we will fully credit your purchase price with the next order. Because of the many variables in the quantity and number of orders you may place, it is impossible to evaluate whether your future order(s) will qualify for this program prior to your placing your next order. Please know American Elements strongly desires to make this free sample program available to you and will make every effort to do so once your next order is placed.
