Cerium Metal Ce CAS 7440-45-1 For Rare Earth Magnetic Material

Cerium is an important rare earth element with an atomic number of 58, and its elemental element is a silver-gray active metal with a content of about 0.0046% in the Earth's crust, which is the highest abundance of rare earth elements. Cerium powder is prone to spontaneous combustion in air, soluble in acid, and is commonly used as a reducing agent. Cerium has a wide range of applications. In the field of optics, it can be used to manufacture optical glass, ceramics and optical instruments, with excellent optical properties and thermal stability. In the electronics industry, cerium is used as an additive to magnetic materials for the manufacture of electronic components, magnetic materials and memory devices. In addition, cerium is also an important raw material for the preparation of automotive exhaust gas purification catalysts and olefin polymerization catalysts, which can improve catalyst performance and reduce the amount of precious metals. In the metallurgical industry, cerium can improve the mechanical properties, thermal stability and corrosion resistance of metals.
