Market applications of rare earth modified stabilizer
And rare earth elements with similar chemical properties anomalous vivid, has a lot of tracks can be used as base ion bear solitary ligand pair of electrons, with rare earth metal ions have a larger ionic radii, the first by electrostatic attraction with inorganic or organic ligands constitute ion coordination bond, as a base for atomic complex, often d2SP3, d4dP3, f3d5Ssp3 other way constitute a hybrid complex with a median of 6-12.
Rare Earth Elements excellent mechanical functions and grouping principles are concerned with the geometric properties of rare earth elements. Because the radius of atoms and ions are important factors resolution crystal structure type, hardness, density and melting point and other physical properties, at normal temperature and pressure conditions, the rare earth lanthanum, praseodymium, neodymium, double-hexagonal crystal structure, and cerium cubic crystal clouds (face-centered) configuration, when the temperature and pressure changes, mostly rare earth attack polymorph change. Because shorten lanthanides, lanthanide atomic radius, atomic volume decreases with the atomic number add, add and add density with atomic number, but cerium and lanthanum, praseodymium, neodymium comparison, there are anomalies.
