Rare Earth Elements: Specialized Materials Used in Modern Technology, Defence, Green Transition
Rare Earth Elements (REEs) are a group of 17 chemically similar metallic elements that are critical to innumerable high-tech applications. Despite their names, most if the REEs are not particularly rare in the Earth's crust—Cerium is as abundant as copper. But the problem is these REEs are rarely found in concentrated form, in economically viable quantities that can be excavated economically, and moreover extracting and processing them is a complex and environmentally challenging process. REEs are used in multiple applications but most importantly in modern electronics, renewable energy, defence systems. Their unique magnetic, luminescent, and catalytic properties make them nearly irreplaceable in many uses. Rare Earth Elements (REEs) derive their value from unique magnetic, luminescent, catalytic, and optical properties. Below is a more comprehensive breakdown by sector and by key individual elements. 17 Rare Eart...
