Thorium Carbide is
available in numerous forms and custom shapes including Ingot, foil, rod, plate and sputtering target. High purity forms also include Carbide powder, submicron powder and nanoscale, single crystal or polycrystalline forms. Thorium Carbide is generally immediately available in most volumes.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. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Like diamond, a pure carbon compound, Carbide compounds tend to be extremely hard, refractory and resistant to wear, corrosion and heat, making them excellent candidates for coatings for drills and other tools. They often have other valuable properties in combination with toughness, such as electrical conductivity, low thermal expansion and abrasiveness.
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.
