CAS 7440-45-1
:Cerium
Description:
Cerium is a silvery-white, ductile metal that belongs to the lanthanide series of the periodic table, with the atomic number 58 and the CAS number 7440-45-1. It is known for its relatively high melting point and is one of the most abundant rare earth elements. Cerium exhibits a variety of oxidation states, most commonly +3 and +4, which contribute to its diverse chemical behavior. It readily oxidizes in air, forming a protective oxide layer, and can react with water at elevated temperatures. Cerium compounds, such as cerium oxide, are widely used as catalysts in automotive catalytic converters and in various industrial applications, including glass polishing and as a component in phosphors for lighting. Additionally, cerium has applications in metallurgy and as an additive in certain alloys to improve their properties. Its unique characteristics make cerium an important element in both industrial and technological contexts.

CAS:<p>Cerium is a rare earth metal and has been studied for its minimal toxicity. Cerium has been shown to be biocompatible and can be used in the treatment of inflammatory diseases. Cerium oxide nanoparticles have been shown to have minimal toxicity and are being studied as a possible drug delivery system for the treatment of osteoarthritis. Cerium has also been shown to have antioxidant activity, which may be due to its ability to scavenge reactive oxygen species or chelate iron. Cerium oxide nanoparticles have also been shown to have potential application in wastewater treatment, as they are able to adsorb organic matter, heavy metals, and radioactive elements.</p>Formula:CePurity:Min. 95%Molecular weight:140.12 g/mol
