Cerium oxide
Overview
Cerium (chemical symbol Ce) is a rare earth metal that belongs to the lanthanide series of the periodic table. Discovered in 1803, cerium is the most abundant of the rare earth elements and is found in various minerals such as monazite and bastnäsite. It is used in a variety of applications due to its unique chemical and physical properties, which make it valuable in both industrial and scientific contexts.
Properties
Cerium has several distinctive properties that contribute to its usefulness. It has an atomic number of 58 and an atomic mass of 140.12 u. Cerium is a soft, silvery-white metal with a density of 6.77 g/cm³. It has a melting point of 798 °C and a boiling point of 3,230 °C. Cerium is relatively reactive and forms a protective oxide layer when exposed to air, which prevents further oxidation. It exhibits both metallic and non-metallic characteristics, making it versatile in various chemical and physical processes.
Applications and Uses
Cerium is employed in a wide range of industrial and technological applications. In the automotive industry, cerium compounds are used in catalytic converters to reduce emissions by facilitating the oxidation of carbon monoxide and unburned hydrocarbons. Cerium dioxide (CeO₂) is also used as a polishing agent for glass and optical lenses due to its abrasive properties and ability to produce a fine, smooth finish.
In materials science, cerium is used to improve the performance of certain alloys and superconductors. Cerium is added to steel and other alloys to enhance their strength and resistance to high temperatures. Additionally, cerium-based compounds are utilised in the production of phosphors for lighting and display technologies, such as LEDs and televisions, where they contribute to the emission of bright, high-quality colours.
Cerium also plays a role in the field of nuclear technology. Cerium-144, an isotope of cerium, is used in radiological research and as a tracer in studies of nuclear reactions. The metal's properties make it useful in a variety of scientific and industrial processes, from materials manufacturing to environmental monitoring.
Safety and Handling
Cerium is generally considered to be of low toxicity, but its compounds can be irritating to the skin, eyes, and respiratory system. Proper safety measures, including the use of personal protective equipment and appropriate handling procedures, should be followed to minimise exposure and ensure safe use.
Summary
Cerium is a rare earth metal with a range of applications, including in catalytic converters, polishing agents, and materials science. Its properties, such as reactivity and ability to form protective oxides, make it valuable for various industrial and technological uses. Testbourne offers high-quality cerium products, ensuring reliable materials for scientific research and industrial applications.
