CAS 7440-27-9: Terbium
Description:Terbium is a chemical element with the symbol Tb and atomic number 65, classified as a lanthanide in the periodic table. It is a silvery-gray metal that is relatively soft and malleable, exhibiting a bright luster when polished. Terbium is known for its high magnetic susceptibility and is used in various applications, including in the production of green phosphors for fluorescent lamps and LED displays. It has a melting point of approximately 1,545 degrees Celsius and a boiling point around 3,230 degrees Celsius. Terbium is not found in its free form in nature but is typically extracted from minerals such as monazite and bastnäsite. It is relatively stable in air, forming a protective oxide layer, but can react with water and acids. Terbium compounds, such as terbium oxide, are utilized in various technological applications, including solid-state devices and as dopants in certain materials to enhance their optical properties. Overall, terbium plays a significant role in modern technology, particularly in the fields of electronics and materials science.
