Scandium Metal (Sc)-Powder

Characteristic

Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element.Scandium metal will turn light yellow or light pink when oxidized in the air, which is easy to burn. It reacts with water to produce hydrogen, and reacts with acid to produce salt. In other chemical properties, it is almost the same as yttrium and other rare earth metal elements. It will not decompose if used   and stored according to specifications. Avoid contact with air, oxides, halogen, moisture.
