What are rare earth elements(REE)?
Rare earth elements stands for a group of seventeen chemical elements that can be found in the periodic table. It consists of yttrium and the other 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium). Scandium is classified as a kind of rare earth element, which can be found in most rare earth element deposits. It is included by IUPAC in the rare earth scale.
The rare earth elements are all metals. They share almost the same properties that makes them being found together. Moreover, they are usually called rare earth oxides because they are sold in the condition of oxide compounds.
Uses of Rare Earth Elements
We are living with various devices containing rare earth metals and alloys nowadays, such as computer memory, DVDs, rechargeable batteries,mobiles, catalytic converters, magnets, fluorescent lighting and so on.
During the past twenty years, there has been leaps and bounds in demand of products made from rare earth metals and alloys. It was rare for people using cell phone twenty years ago, but today, there are almost 7 billion citizens living with cell phones as well as computers and can not get rid of them, which indicates that rare earth elements are extremely in need than any period before.
With the growing demand for portable electronic devices such as mobiles, more rechargeable batteries are also required. In turn, being as the essential parts of batteries, rare earth compounds are in larger demand than ever. Rare earth elements are suitable for many other electronic devices such as laptops and cameras.
Nowadays, we are pursuing more ways in discovering or creating sustainable energy for the developing world. As concerns for the energy independence, climate change and other issues drive the demand of electric and hybrid vehicles, the need of batteries made from rare earth compounds will grow faster than ever.
Rare earths are applied in catalysts, phosphors, and polishing compounds. These are used for air pollution control, illuminated screens on electronic devices, and the polishing of optical-quality glass. All of these products are expected to experience rising demand.
There are other substances that can replace rare earth elements in many aspects. However, they are less effective and costly.
