Even futuristic technologies need these REMs For example high-temperature superconductivity safe storage and transport of hydrogen for a post-hydrocarbon economy environmental global warming and energy. This chart shows the use of rare earth elements in the United States during 2020.

Due to use of REEs in many major manufacturing techniques and their presence in many consumer electronics it is certain that decrease in supply would affect prices across a wide range of sectors.
Rare earth element usage. Functional ceramic is a new type of ceramic material for. The rare earths are a relatively abundant group of 17 elements composed of scandium yttrium and the lanthanides. The rare in the name of this group of elements is actually somewhat misleading.
Within the last decade these elements have become extremely sought after. Rare earth metals are actually not as rare as their name might imply. Many vehicles use rare earth catalysts in their exhaust systems for air pollution control.
A large number of alloys are made more durable by the addition of rare earth metals. In geochemistry rare-earth elements can be used to infer the petrological mechanisms that have affected a rock due to the subtle atomic size differences between the elements which causes preferential fractionation of some rare earths relative to others depending on the processes at work. Rare earth elements are used in medicine and defense applications and in alloys electronics lighting and display screens for applications in aerospace.
It clearly shows the United States entry into. Rare-earth elements REEs are used as components in high technology devices including smart phones digital cameras computer hard disks fluorescent and light-emitting-diode LED lights flat screen televisions computer monitors and electronic displays. For example they have been applied in functional ceramic.
REE - Rare Earth Elements and their Uses The demand for rare earth elements has grown rapidly but their occurrence in minable deposits is limited. The principal economic sources of rare earths are the minerals bastnasite monazite and loparite and the lateritic ion-adsorption clays. Lesser amounts of dysprosium gadolinium and praseodymium are also used in these magnets.
Usage of Rare Earth Elements REE in Emerging technologies They are being used in anything and everything that comes out as an innovative product nowadays for example from I-phones to I-TV and many other devices that people use every day such as computer memory DVDs rechargeable batteries cell phones catalytic converters magnets fluorescent lighting and much more. According to OICA the total number of motor vehicles produced in 2019 in China and India are 2575 million units and 452 million units respectively. With increasing investments in the healthcare industry and the rising ceramic demand and production the consumption of rare earth elements is projected to increase noticeably in the region.
Geological Survey describes them as relatively abundant in the Earths crust But extraction is. Rare-earth element any member of the group of chemical elements consisting of three elements in Group 3 scandium Sc yttrium Y and lanthanum La and the first extended row of elements below the main body of the periodic table cerium Ce through lutetium Lu. Rare earth elements are used to produce camera lenses container glass paint thinner water treatment agents fertilizers and thermal barrier coatings that protect jet engines during operation.
Uses of rare earth elements. This chart shows a history of rare earth element production in metric tons of rare earth oxide equivalent between 1950 and 2015. Global consumption value distribution of rare earths by element 2018 Demand for rare earth oxides worldwide by application 2019 2025 The most important statistics.
Currently these metals have become very critical to several modern technologies ranging from cell phones and. Significant uses include hard disk drives cell phones electric motors for hybrid vehicles and windmills and actuators in aircraft Goonan 2011. Its usage range from daily use eg lighter flints glass polishing mediums car alternators to high-end technology lasers magnets batteries fibre-optic telecommunication cables.
The large amounts of rare earths used in green energy mean that significant price increases in REEs would result in large price increases in green tech. Rare Earths Functional Ceramic Rare Earth Elements consist of 17 metal elements including 15 lanthanides scandium and yttrium. The elements range in crustal abundance from cerium the 25th most abundant element of the 78 common elements in the Earths.
The elements cerium through lutetium are called the lanthanides but many. Rare earth elements are used in mature markets such as catalysts glassmaking lighting and metallurgy which. In recent 20 years rare earth elements have made great contributions to the developments of high-tech industries.
The end uses of rare earths include the production of magnets catalyzers displays. They are critical to high-performance optics and lasers and essential to the most powerful magnets and superconductors in the world. Rare Earth Oxides are used in mature markets such as catalysts glassmaking and metallurgy which account for 59 of the total worldwide consumption of rare earth elements and in newer high-growth markets such as battery alloys ceramics and permanent magnets which account for 41 of the total worldwide consumption of rare earth elements.
Account for 59 percent of the total worldwide consumption of rare earth elements and in newer high-growth markets such as battery alloys ceramics and permanent magnets which account for 41 percent of the total worldwide. Rare earths are simply more expensive to mine than most metals when not mined with environmentally harmful chemicals. Kingsnorth IMCOA rare earth oxide REO consumption in the permanent magnet sector increased from 24 000 tons in 2012 to 50 000 tons in 2016 thus representing 31 of global demand compared to 20 in 2012 Figure 2.
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.
