American Elements specializes in producting Tantalum-based furnace components for crystal synthesis and other applications. Typical furnace elements can include boats, carriers, crucibles, spacers, hangers, crowns, heating elements (wire, rod, mesh), hot zone components, rod (threaded, gun drilled), sheet (dimpled), shells & mantels, shielding components, tubing, shims, supports, and fasteners. American Elements can produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and 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 numerous other machined shapes and in the form of solutions and organometallic compounds. Ultra high purity and high purity forms also include metal powder, submicron powder and nanomaterials, targets for thin film deposition, and pellets for chemical vapor deposition (CVD) and physical vapor deposition (PVD) applications. 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. Typical and custom packaging is available, as is additional technical and safety (MSDS) data. Please contact us for information on lead time and pricing above.

Tantalum Bohr ModelThe number of electrons in each of tantalum's shells is [2, 8, 18, 32, 11, 2] and its electron configuration is [Xe] 4f14 5d3 6s2. The tantalum atom has a radius of 146 pm and a Van der Waals radius of 217 pm. High Purity (99.999%) Tantalum (Ta) MetalTantalum was first discovered by Anders G. Ekeberg in 1802 in Uppsala, Sweden however, it was not until 1844 when Heinrich Rose first recognized it as a distinct element. In its elemental form, tantalum has a grayish blue appearance. Tantalum is found in the minerals tantalite, microlite, wodginite, euxenite, and polycrase. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology.

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.
