Know About Rare Earths

What Are Rare Earths?

Rare earth elements are relatively plentiful in the earth;s crust, with cerium being the 25th most abundant element at 68 parts per million. This makes it as abundant as copper. Because of thier geochemical properties, rare earth ellemnts are typically dispersed. This means they are nit often found in concentrated enough clusters to make them visible to mine. It was the scarcity of these minerals that led to them being called rare earths.

Rare Earths are a group of 17 elements in the periodic table known as the Lanthanide series, plus Yttrium. Rare earths are categorised into light elements (lanthanum to samarium) and heavy elements (europium to lutetium). The latter are less common and consequently more expensive.

Chemically, rare earths are strong reducing agents. Their compounds are generally ionic and they display high melting and boiling points. Rare earths are relatively soft when in their metallic state while those with a higher atomic number tend to be harder. Rare earths react with other metallic and non-metallic elements to form compounds each of which has specific chemical behaviours. This makes them indispensable and non-replaceable in many electronic, optical, magnetic, and catalytic applications. Rare earth compounds are commonly fluorescent under ultraviolet light, which can assist in their identification. Rare earths also react with water or diluted acid to produce hydrogen gas.

Where Are Rare Earths Found?

Minerals containing rare earths are currently produced in seven countries and regions including China, Russia, the US, Australia, India, Brazil, and Malaysia. Lanthanum and cerium accounted for nearly 60% of world consumption of rare earths in 2012 followed by neodymium, yttrium, and praseodymium.
The first rare earth was discovered in 1787 in a village in Sweden. Since then they have become technologically, environmentally, and economically important across the globe.

YTTRIUM

Yttrium or Y (39) is a non-lanthanide rare earth element used to produce superconductors, powerful pulsed lasers, cancer treatment drugs, rheumatoid arthritis medicines, and surgical supplies. Silvery metal in colour, it is also used in many popular consumer products such as televisions and camera lenses.

LANTHANUM

Lanthanum or La (57) is a silver-white metal that is one of the most reactive rare earth elements. It is used in the manufacture of specialised optical glasses including infrared absorbing glass as well as camera and tele scope lenses.

CERIUM

Cerium or Ce (58) is a silvery-white metal that easily oxidises in the air. It is the most abundant rare earth elements and has many uses including as catalyst in catalytic converters in automotive exhaust systems reduce emissions. It is also a key component for precision glass polishing.

PRASEODYMIUM

Praseodymium or Pr (59) this soft, silvery metal was first used to create a yellow-orange stain for ceramics. Although it is still used to colour certain types of glasses and gemstones, praseodymium is primarily used in rare earth magnets.

NEODYMIUM

Neodymium or Nd (60) is a soft, silvery metal, neodymium that is used with praseodymium to create some of the strongest permanent magnets available in the world today. These magnets are found in most modern vehicles and aircraft as well as popular consumer electronics such as headphones, microphones, and computer discs.

PROMETHIUM

Promethium or Pm (61) is the only naturally radioactive rare earth element. Virtually all promethium in the earth's crust has long ago decayed into other elements. Today, it is largely artificially created, and used in watches, pacemakers, and a scientific research applications.

SAMARIUM

Samarium or Sm(62) is a silver metal that can be used in several vital ways including in very powerful magnets for transporation, defence, and commercial technologies. In conjunction with other compounds, it can also be used for instravenous radiation treatments to kill cancer cells.

EUROPIUM

Europium or Eu(63) is a hard metal used to create visible light in compact fluorescent bulbs and color displace such as in LCD televisions. It is also used to make the special phosphors marks on the Euro notes to help prevent counterfeiting.

GADOLINIUM

Gadolinium or Gd(64) has particular properties that make it especially suitable for shielding in nuclear reactors and neutron radiography. It is also used to help target tumours in neuron therapy as well as enhance magnetic resonance imaging.

TERBIUM

Terbium or Tb (65) is a silvery rare earth metal that is so soft it can be cut with a knife. Terbium is often used in compact fluorescent lighting, colour displays, and as an additive to permanent rare earth magnets so they can function better under higher temperatures.

DYSPROSIUM

Dysprosium or Dy (66) [-'eis a soft, silver metal with one of the highest magnetic strengths of all of the rare earths, matched only by holmium. Dysprosium is often added to permanent rare earth magnets to help them operate more efficiently at higher temperatures.

HOLMIUM

Holmium has incredible magnetic properties. Infact some of the strongest artificially created magnetic fields are the result of magnetic flux concentrators made with holmium alloys. As well as providing coloring to cubic zirconia and glass, holmium and also be used in nuclear control rods.

ERBIUM

Erbium or Er is widely used in nuclear applications such as neutron absorbing control rods. It is a key component of high-performance fiber optic communication system. It can also be used to provide glass and other materials a pink color for asthetic as well as specific industrial purposes.

THULIUM

Thulium or Tm(69) is a silvery-gray metal and one of the least abundant rare earths. Its Isotopes are widely used as the radiation device in portable x-rays which makes thulium a highly useful material. Thulium is also component of highly efficient lasers which are used in the defence medical and meteorology sectors.

YTTERBIUM

Ytterbium or Yb(70) has several important uses in health-care including in certain cancer treatments. Ytterbium can also enhance stainless steel as well as help monitor the effects of earthquakes and explotions on the ground.

LUTETIUM

Lutetium or Lu(71) is the last of the rare earth elements and has several interesting uses. For example, Lutetium isotopes can help reveal the age of ancient items such as meteorites. It also has applications related to petroleum refining and positron emissions tomography.

SCANDIUM

Scandium is one of the rare chemicals, that can be found in houses in equipement such as color televisions, fluorescent lamps, energy-saving lamps and glasses. The use of scandium is still growing, due to the fact that it is suited to produce catalysers and to polish glass.

Gemstones

Precious Gemstones

Diamonds

Diamonds are brilliant, illustrious carbon minerals knowns as the king of gemstones.

As one of the hardest minerals on earth, diamond's structure and global prestige are virtually unbreakbale. While roughly 98% of all gems are considred semi-precious, dimaond is one four gems on the list of precious stones along with ruby, sapphire, and emerald.

Ruby

Ruby is a type of rare mineral called corundum.

In fact, the only other variety of corundum is sapphire. Sapphires and rubies are ample and abundant, but they naturally have notoiety since they are from a rare and durable mineral class. When it comes to precious gemstones, nothing beats the classic ruby! This royal red jewel is treasured worldwide.

Sapphire

Sapphire is the famous gem from the corundum mineral class, alongside its sister gem, ruby.

However, pure corundum is colorless. Its the presence of trace impurities in the stones's chemical structure that influence each gems's color. Otherwise, all sapphires would be colorless.

Emerlad

Emerald is atype of mineral called beryl, inarguably the most well-known of its kind.

Other beryl gems include aquamarine, goshentie, morganite, heliodor, and red beryl. Emerald stones make for dazzling rings, brooches, and pendants.
