Lanthanum

Description:
Lanthanum is a silvery-white, ductile metal that belongs to the lanthanide series of the periodic table, with the atomic number 57 and the CAS number 7439-91-0. It is characterized by its relatively high melting point and density compared to other metals. Lanthanum is known for its ability to absorb moisture and is typically stored in an inert atmosphere or oil to prevent oxidation. It exhibits a +3 oxidation state in most of its compounds, which are often ionic and can form various salts and oxides. Lanthanum is used in various applications, including in the production of high-intensity carbon-arc lights, as a catalyst in petroleum refining, and in the manufacture of certain types of glass and ceramics. Additionally, lanthanum compounds are utilized in the production of phosphors for color television tubes and LED lights. Its unique properties make it an important element in both industrial and technological applications, particularly in the fields of electronics and materials science.
