Rare earth elements: A review of applications

Rare earth elements (REE) include the lanthanide series elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. Currently these metals have become very critical to several modern technologies ranging from cell phones and televisions to LED light bulbs and wind turbines.

Rare-earth element

As seen in the chart to the right, rare-earth elements are found on earth at similar concentrations to many common transition metals. The most abundant rare-earth element is cerium, which is actually the 25th most abundant element in Earth's crust, having 68 parts per million (about as common as copper).The exception is the highly unstable and radioactive promethium "rare …

Baryte

Baryte, barite or barytes (/ ˈ b ær aɪ t, ˈ b ɛər-/ or / b ə ˈ r aɪ t iː z /) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution ...

Lithium

Lithium (from Greek: λίθος, romanized: lithos, lit. 'stone') is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal.Under standard conditions, it is the least dense metal and the least dense solid element.Like all alkali metals, lithium is highly reactive and flammable, and must be stored in vacuum, inert atmosphere, or inert liquid such …
