An Overview On Rare Earth Materials

Introduction

Rare Earth Elements play a central role in various industrial applications owing to their distinct physical and chemical properties. This article examines the importance of rare earth elements, their global distribution, and the specific applications in which their properties are used.

Rare Earth Elements and Global Occurrence

China, Russia, the United States, Australia, and India are the primary suppliers of rare earth reserves worldwide. Significant minerals such as bastnäsite, monazite, and ion-adsorbed rare earths are of strategic relevance for the global allocation of resources.

Understanding Rare Earth Elements

According to the International Union of Pure and Applied Chemistry, rare earth elements consist of 15 lanthanides. Their atomic numbers range from 57 to 71. Scandium and Yttrium are also included because of their similar electronic structures and chemical properties.

Classification of Rare Earth Elements

The distinct physical and chemical differences between rare earth elements result in their categorisation into light and heavy groups. The first seven elements up to Gadolinium are designated as light rare earth elements, while subsequent elements, including Gadolinium, are classed as heavy rare earth elements. Yttrium, despite its lower atomic weight, is closely associated with the heavy rare earth elements because of its ionic radius.

Applications in Various Sectors

Rare earth elements are used in many industries. They contribute to the manufacture of fluorescent materials, components for metal hydride batteries, electric light sources, permanent magnets, and hydrogen storage solutions.

They also support the production of catalytic materials, precision ceramics, lasers, superconductors, magnetostrictive materials, magnetically cooled devices, magneto-optical storage systems, and optical fibre materials.

SAM's Expertise in the Provision of Rare Earth Elements

With over two decades of experience, Stanford Advanced Materials (SAM) is a reliable supplier of rare earth metals and compounds. SAM offers a range of rare earth materials, excluding radioactive promethium, and maintains quality and competitive prices. Rare earth oxides are available in multiple stocks and can be delivered promptly upon order confirmation.
