An Overview on Rare Earth Materials
Introduction
Rare earth materials, with their distinctive physical and chemical properties, play a pivotal role in various industrial applications. This article delves into the significance of rare earth elements, their global presence, and the diverse range of applications that leverage their unique characteristics.
Rare Earth Elements and Global Deposits
China, Russia, the United States, Australia, and India stand as major contributors to the world's rare earth deposits. Noteworthy minerals like bastnaesite, monazite, and ion-adsorbed rare earth mines hold strategic importance in global resource distribution.
Understanding Rare Earth Elements
As defined by the International Federation of Pure and Applied Chemistry, rare earth elements consist of 15 lanthanides with atomic numbers ranging from 57 to 71. This group, situated in the third subgroup of the Mendeleev periodic table, includes scandium and yttrium due to their analogous electronic structure and chemical properties.
Categorization of Rare Earth Elements
The distinct physical and chemical variances among rare earth elements lead to their classification into light and heavy groups. The first seven elements, up to gadolinium, are termed light rare earth elements, while those beyond, including gadolinium, are classified as heavy rare earth elements. Despite its lower atomic weight, Yttrium aligns closely with heavy rare earth elements due to its ion radius within the ion radius chain of this subgroup.
Applications Across Industries
Rare earth materials find application in an extensive array of industries, contributing to the production of fluorescent materials, metal hydride battery components, electric light sources, permanent magnets, hydrogen storage solutions, catalytic materials, precision ceramics, lasers, superconductors, magnetostrictive materials, magnetically cooled devices, magneto-optical storage, and optical fiber materials.
