Thorium Oxide is a highly insoluble thermally stable Thorium source suitable for glass, optic and ceramic applications. Thorium Oxide 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. Thorium is highly valued in glass and ceramic production as a bright yellow pigment because of its optimum reflectance at 560 nm. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. Rare Earth oxide compounds are basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. They are compounds containingat least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Thorium oxide is also available in rod, tubes, wire, slugs, sputtering targets, foil, plate, ribbon, sheet, shot, and Spheres. Additional technical, research and safety (MSDS) information is available.

Thorium is a Block F, Group 3, Period 7 element. The number of electrons in each of Thorium's shells is 2, 8, 18, 32, 18, 10, 2 and its electronic configuration is [Rn] 6d² 7s². In its elemental form thorium's CAS number is 7440-29-1. The thorium atom has a radius of 179.8.pm and it's Van der Waals radius is 200.pm. Thorium is radioactive and can collect in bones which may cause bone cancer several years after exposure. Breathing in substantial amounts of thorium may be lethal. Thorium is a lanthanide (rare earth) material with potential nuclear power applications. Thorium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. It is presently used as a tungsten coating in electronic parts due to its high emission factor. Thorium in the form of its fluoride and oxide is used in advanced optic applications for its high refractive index. It is also used in several other high temperature glass applications, such as in the mantle of lamps and to produce crystal growth crucibles and ampules. Thorium was first discovered by Jons Berzelius in 1828. The name Thorium originates from the Scandinavian god, Thor, the Norse god of war and thunder. See Thorium research below.
