Zirconium Scandium Iron Alloy is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered.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.
Zirconium is a Block D, Group 4, Period 5 element. The number of electrons in each of Zirconium's shells is 2, 8, 18, 10, 2 and its electronic configuration is [Kr] 4d2 5s2. In its elemental form zirconium's CAS number is 7440-67-7. The zirconium atom has a radius of 159.pm and it's Van der Waals radius is 200.pm. Zirconium is non-toxic. Zirconium is primarily used in it's oxide or zirconia form. Zirconium dioxide has a high melting point (2,700° C) and a low thermal conductivity. Its polymorphism, however, restricts its widespread use in ceramic industry. During a heating process, zirconia will undergo a phase transformation process. The change in volume associated with this transformation makes the usage of pure zirconia in many applications impossible. Addition of some oxides, such as CaO, MgO, and Y2O3, into the zirconia structure in a certain degree results in a solid solution, which is a cubic form and has no phase transformation during heating and cooling. This solid solution material is termed as stabilized zirconia, a valuable refractory. Stabilized zirconia is used as a grinding media and engineering ceramics due to its increased hardness and high thermal shock resistivity. Stabilized zirconia is also used in applications such as oxygen sensors and solid oxide fuel cells due to its high oxygen ion conductivity.Zirconium was first discovered by William Gregor in 1791. The name Zirconium originated from the Persian word 'zargun' meaning gold color or gold-like. See Zirconium research below.
Scandium is a Block D, Group 3, Period 4 element. The number of electrons in each of Scandium's shells is 2, 8, 9, 2 and its electronic configuration is [Ar] 3d1 4s2. In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is mildly toxic. Scandium is a metal that has many of the characteristics of the rare earth elements, particularly yttrium. It is a light material with a higher melting point than aluminum giving uses in aerospace and most recently, in racing bicycles and golf clubs. Doping zirconium oxide with scandium oxide produces a low temperature electrolyte in solid oxide fuel cells. Scandium information, including Technical Data, Safety Data and its high purityproperties, research, applications and other useful facts are discussed here. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included. Scandium was first discovered by Lars Nilson in 1879. The origin of the name, Scandium, comes from the Latin word 'Scandia' meaning Scandinavia. See Scandium research below.
Iron is a Block D, Group 8, Period 4 element. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electronic configuration is [Ar] 3d6 4s2. In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pm and it's Van der Waals radius is 200.pm. Iron is not toxic. Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Recent applications for Iron nanoparticles include in water treatment of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in certain alloy and catalyst applications. Iron can also be introduced into processes using iron foil, pellets, rod and wire by thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Iron 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. Iron was first discovered by Early Man.See Iron research below.

In its elemental form scandium's CAS number is 7440-20-2. The scandium atom has a radius of 160.6.pm and it's Van der Waals radius is 200.pm. Scandium is mildly toxic.

The origin of the name, Scandium, comes from the Latin word 'Scandia' meaning Scandinavia. See Scandium research below.
Iron is a Block D, Group 8, Period 4 element. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electronic configuration is [Ar] 3d6 4s2. In its elemental form iron's CAS number is 7439-89-6. The iron atom has a radius of 124.1.pm and it's Van der Waals radius is 200.pm. Iron is not toxic. Iron is the most commonly used metal for commercial applications due to its hardness, historical availability and low cost. Once used on its own, it is now alloyed with nickel and other elements to produce steel and other high strength, non-corrosive structural metals. Iron as a metal and as its 
many compounds has numerous uses. It is a primary colorant in glass and ceramics. It is a catalyst. It is the basis for low grade magnets and because of its magnetic properties is used extensively in memory tape. Recent applications for Iron nanoparticles include
in water treatment of carbon tetrachloride in contaminated groundwater, magnetic data storage and resonance imaging (MRI) and in certain alloy and catalyst applications. Iron can also be introduced into processes using iron foil, pellets, rod and wire by thin film 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), Organometallic and Chemical Vapor Deposition (MOCVD) for specific applications such as fuel cells and solar energy. Iron 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. Iron was first discovered by Early Man.See Iron research below.
