Cerium
is a chemical element with the symbol Ce and atomic number 58, belonging to the lanthanide rare earth metals. Here is an introduction about it:
Basic information: The atomic weight is approximately 140.116, the density is 6.770g/cm3, the melting point is 799 ° C, the boiling point is 3443 ° C, and the electronic configuration is [Xe] 4f15d16s2
Discovery history: In 1803, Swedish chemists Jacob Berzelius and Wilhelm von Heisinger, as well as German chemist Martin Craplos, independently discovered Pu, which was named after the English name of Ceres.
Physical properties: Cerium is a soft and ductile metal, with colors ranging from commercial grade iron gray to relatively pure silver. It has a certain degree of magnetism and becomes antiferromagnetic below -260.15 ° C. At pressures above 20Kbar, it becomes superconducting in the millikelvin range
-Chemical properties: The chemical properties are relatively active and generally need to be stored in vacuum or inert gas. It can be corroded by alkaline solutions and quickly dissolved in diluted acids, except for hydrofluoric acid. There are two common oxidation states,+3 and+4, with+4 valence compounds exhibiting strong oxidizing properties.
-Preparation method: The main method used is molten salt electrolysis, which uses rare earth compounds as raw materials and is divided into two processes: chloride and oxide molten salt electrolysis. It can produce metal pavements with a purity of 99.0% to 99.5%.
-Application areas: In the steel industry, it can purify molten steel and improve the performance of steel; In non-ferrous metals and their alloys, it can improve their ductility, oxidation resistance, etc; It can also be used to make ignition alloys, hydrogen storage materials, rare earth permanent magnet alloys, etc. In addition, oxidation can be used as a decolorizing and clarifying agent, polishing agent, etc. in the glass and ceramic industry.
