TZM Molybdenum Alloy Sputtering Targets are available as disc, granules, ingot, pellets, pieces, powder , rod, wire, tube and in numerous other forms and custom shapes. 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 Pharmacopeia/British Pharmacopeia) and follows applicable ASTM testing standards.See safety data and research below and pricing/lead time above. TZM is Molybdenum's prime alloy and is an alloy of titanium, zirconium and carbon. TZM is stronger than Molybdenum alone withstanding temperatures over 1300 °C and provides better weldability and overall strength.

Molybdenum is a Block D, Group 6, Period 5 element. The number of electrons in each of Molybdenum's shells is 2, 8, 18, 13, 1 and its electronic configuration is [Kr] 4d5 5s1. In its elemental form molybdenum's CAS number is 7439-98-7. The molybdenum atom has a radius of 136.3.pm and it's Van der Waals radius is 200.pm. Molybdenum is toxic unless it is in small quantities. Molybdenum has the third highest melting point of any element, exceeded only by tungsten and tantalum. Molybdenum is a catalyst in the oil refining. It has many other applications, including in catalysts, pigments, corrosion inhibitors and lubricants. It has a very high elastic modulus. Molybdenum 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 used in steel alloys to add hardness and raise melting points. It is a component in Hastelloys brand steel. Molybdenum is used in nuclear reactors and aerospace components. Molybdenum was first discovered by Carl Wilhelm in 1778. The origin of the name Molybdenum comes from the Greek word molubdos meaning lead. See Molybdenum research below.
Selenium is a Block P, Group 16, Period 4 element. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. The EPA does not classify selenium as carcinogenic, although selenium sulfide is a probable carcinogen. Selenates and selenites which are compounds of selenium, are highly toxic. Hydrogen selenide gas (SeH2) is the most acutely toxic compound of selenium. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. Selenium is available as metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Selenium was first discovered by Jons Berzelius in 1817. The origin of the name Selenium comes from the Greek word "Selênê" meaning moon. See selenium research below.
