Currently these metals have become very critical to several modern technologies ranging from cell phones and.

Rare earth elements used in electronics. Rare-earth elements REE are necessary components of more than 200 products across a wide range of applications especially high-tech consumer products such as cellular telephones computer hard drives electric and hybrid vehicles and flat-screen monitors and televisions. Rare earth elements are the secret sauce of numerous advanced materials for energy transportation defense and communications applications. Although tantalum is not one of the rare earths -- it is one of the transition metals like gold -- tantalums scarcity 1 or 2 ppm of the earths crust and primary use in electronics tantalum capacitors fits in with the scope of this question.

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. 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. Holmium - another rare earth element with powerful magnetic properties used in the microwave equipment and nuclear control rods.

Generally rely on rare earth metals. The reserves of some rare earth minerals used in electronics medical equipment and renewable energy could run out in less than 100 years. For example color cathode-ray tubes and liquid-crystal displays used in computer monitors and televisions employ europium as the red phosphor.

Other rare earths are also commonly used in electronic devices today. Some of the rare-earth metals and their atomic weights that are commonly used in electronics include lanthanum 57 cerium 58 neodymium 60 samarium 62 europium 63 terbium 65 and dysprosium. These small devices made possible a global network of long fiber-optic cables that reduced the price of long-distance telephone calls and now carry.

Geological Survey news release Going Critical explains. Rare-earth elements in this category are used in the electric motors of hybrid and electric vehicles generators in wind turbines hard disc drives portable electronics microphones speakers. But the Chinese have a lock on the production of rare earth elements and this could become a problem for the US.

No substitute is known. Column 3 of the Periodic Table of Elements Lists the Rare Earths. Some Applications of the Rare Earth Elements Many applications of REE are characterized by high specificity and high unit value.

Many of these rare earth elements and tech metals are critical ingredients of our high-tech devices 2. Some are present in only very small quantities in the Earths crust. Erbium is used in lasers and fiber optic cables.

Metals used in military weapons and electronic weapons systems. Fifteen of those elements are in the lanthanide series and two additional elements share similar chemical properties. Rare earth minerals are very important to todays electronics.

Terbium - a soft silvery metal used as an additive in rare earth magnets in some electronic devices and in sonar systems. Cerium is apparently as abundant as copper. Your iPod laptop and television use them.

Published Monday September 14 2020. Holmium - another rare earth element with powerful magnetic properties used in the microwave equipment and nuclear control rods. Dysprosium is mixed within alloys used in wind turbines electric vehicles and nuclear reactors.

Large quantities of some REEs are used in clean energy and defense technologies. Europium is used in light bulbs nuclear reactors. Neodymium atomic number 60 for instance is a powerful magnet useful in smartphones televisions lasers rechargeable.

Rare earth minerals are naturally occurring resources which cannot be recreated or replaced. Ce La and Nd are important in alloy making and in the production of fuel. Scandium and Yttrium are listed as rare earth metals although they are not part of the lanthanide series.

They make electronics light so they dont need much power. They are regarded as rare because deposits of these elements are. Terbium - a soft silvery metal used as an additive in rare earth magnets in some electronic devices and in sonar systems.

There are 17 rare earth elements all vital to the electronics industry in some form. Metals In Military Weaponry Technology Electronics. Found in the Earths crust rare earths are critical elements used in cars consumer electronics computers communications clean energy and defense systems.

Cerium is used in light bulbs TVs and ovens. Examples are permanent magnet materials ie. Samarium cobalt SmCo and neodymium iron boron NdFeB They are used in technology like precision-guided missiles smart bombs and aircraft.

This is due to the prevalence of the two elements being similar in part to the lanthanides. Yet despite their name some rare earth elements are relatively plentiful. Use of rare earth elements in electronics expanded through the 1990s and the 2000s.

In the early 1990s Bell Labs developed the erbium-doped fiber amplifier to boost the signal in fiber-optic cables. Their largest use for clean energy is.
