Niobium Aluminide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. As aluminium is near the nonmetals, it bonds with metals differently than other metals, consequently the properties of aluminide compounds are intermediate between those of a metal alloy and an ionic compound.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.
Niobium is a Block D, Group 5, Period 5 element. The number of electrons in each of Niobium's shells is 2, 8, 18, 12, 1 and its electronic configuration is [Kr] 4d4 5s1. In its elemental form niobium's CAS number is 7440-03-1. The niobium atom has a radius of 142.9.pm and it's Van der Waals radius is 200.pm. Some niobium compounds are considered very toxic. Niobium is the basis for various barium titanate compositions used as dielectric coatings in telecommunications and small advanced electronics, such as cell phones, pagers and laptop computers. Niobium 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. Niobium has medical research applications. It is alloyed to produce arc-welding rods and in corrosion-resistant steel. Niobium was first discovered by Charles Hatchett in 1801. The word Niobium originates from Niobe, daughter of mythical Greek king Tantalus. See Niobium research below.
Aluminum is a Block P, Group 13, Period 3 element. The number of electrons in each of Aluminum's shells is 2, 8, 3 and its electronic configuration is [Ne] 3s2 3p1. In its elemental form aluminum's CAS number is 7429-90-5. The aluminum atom has a radius of 143.2.pm and it's Van der Waals radius is 200.pm. Aluminum is the most abundant metal in the earth's crust. Aluminum is not known to be harmful but ingestion may cause Alzheimer's disease.Aluminum is a silvery-white metal that possesses many desirable characteristics. It is light, nonmagnetic and nonsparking.
It stands second among metals in the scale of malleability, and sixth in ductility. It is extensively used in many industrial applications where a strong, light, easily constructed material is needed. Although it's electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. They are used to coat telescope mirrors. Aluminum 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. See Aluminum research below.
An aluminide contains aluminium and one or more electropositive elements. Since aluminum is similar to the nonmetals, it forms compounds with properties intermediate between a metal alloy and an ionic compound. Aluminides have found applications in hydrogen storage technology, the aeronautical industry, and in coatings for furnaces and other high temperature applications.
