 Vanadium Silicide 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.
 Vanadium is a Block D, Group 5, Period 4 element. The number of electrons in each of Vanadium's shells is 2, 8, 11, 2 and its electronic configuration is [Ar] 3d3 4s2. In its elemental form vanadium's CAS number is 7440-62-2. The vanadium atom has a radius of 131.1.pm and it's Van der Waals radius is 200.pm. Several vanadium compounds are toxic to some creatures despite the fact that it is an essential trace element. Vanadium is highly resistant to corrosion, so it is commonly used to alloy stainless steel grades. Vanadium compounds are used in advanced ceramics. Vanadium is a petrochemical cracking catalyst. Vanadium 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. Vanadium information, including Technical Data, Safety Data and its high purity properties , 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. Vanadium was first discovered in Mexico City by Andres Manuel del Rio, a Spanish born and European educated Mexican mineralogist, in 1801. In honor of its beautiful multi-colored compounds, Vanadium was named after the word "Vanadis" meaning goddess of beauty in Scandinavian mythology. See Vanadium research below.  Silicon is a Block P, Group 14, Period 3 element. The number of electrons in each of Silicon's shells is 2, 8, 4 and its electronic configuration is [Ne] 3s2 3p2. In its elemental form silicon's CAS number is 7440-21-3. The silicon atom has a radius of 117.6.pm and it's Van der Waals radius is 210.pm. Silicon is not toxic but can cause chronic respiratory problems if inhaled as a fine silica or silicate dust. Asbestos silicates are carcinogenic. Silicon is one of man's most useful elements. It makes up 25.7% of the earth's crust, by weight, and is the second most abundant element, being exceeded only by oxygen. The Czochralski process is commonly used to produce single crystals of silicon used for solid-state or semiconductor devices. Silica, as sand, is a principal ingredient of glass, one of the most inexpensive of materials with excellent mechanical, optical, thermal, and electrical properties. Silicon 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. Ultra high purity silicon can be doped with boron, gallium, phosphorus , or arsenic to produce silicon for use in  transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries. Hydrogenated amorphous silicon has shown promise in producing economical cells for converting solar energy into electricity. Silcones are important products of silicon. They range from liquids to hard, glasslike solids with many useful properties. Silicon was first discovered by Jons Berzelius in 1823. The name Silicon originates from the Latin word "silex" which means flint or hard stone. See Silicon research below.
