Scandium is a chemical element with the symbol Sc and atomic number 21. It is a silvery-white metallic d-block element.  The properties of scandium compounds are intermediate between those of aluminium and yttrium. A diagonal relationship exists between the behavior of magnesium and scandium, just as there is between beryllium and aluminium. In the chemical compounds of the elements in group 3, the predominant oxidation state is +3.  ATT provides Scandium and compounds at a competitive price, including Scandium Acetate, Scandium Aluminium Alloy, Scandium Carbonate, Scandium Chloride, Scandium Fluoride, Scandium Hydroxide, Scandium Metal, Scandium Nitrate, Scandium Oxalate, Scandium Oxide, Scandium Sulfate.
