Yttrium: the essentials Erbium is never found in nature as the free element. Erbium is found in the ores monazite sand [(Ce, La, etc.)PO 4 ] and bastn°site [(Ce, La, etc.)(CO 3)F], ores containing small amounts of all the rare earth metals. It is difficult to separate from other rare earth elements.

Erbium A trivalent element, pure erbium metal is malleable (or easily shaped), soft yet stable in air, and does not oxidize as quickly as some other rare-earth metals. Its salts are rose-colored, and the element has characteristic sharp absorption spectra bands in visible light, ultraviolet, and near infrared.

Rare-earth element Despite their name, rare earth elements are – with the exception of the radioactive promethium – relatively plentiful in Earth's crust, with cerium being the 25th most abundant element at 68 parts per million, or as abundant as copper.are earth elements became known to the world with the discovery of the black mineral Ytterbite (renamed to Gadolinite in 1800) by Lieutenant Carl Axel Arrhenius in 1787, at a quarry in the village of Ytterby, Sweden.

Francium Francium is a chemical element with symbol Fr and atomic number 87. It was formerly known as eka-caesium and actinium K. It is the second-least electronegative element, behind only caesium. Francium is a highly radioactive metal that decays into astatine, radium, and radon. As an alkali metal, it has one valence electron. Bulk francium has never been viewed.

- Background: Zirconium (Zr) is a grayish-white, metallic element with an atomic number of 40. It naturally combines with silica and oxygen to form the mineral zircon (ZrSiO4), the primary ore of this element.irconium is used in a number of industrial applications because it is so resistant to corrosion. It is used in pumps and valves and the cores of nuclear reactors. Zirconium oxide is used to make laboratory crucibles and to line furnaces.

What Are Rare Earths? There are 17 elements that are considered to be rare earth elements—15 elements in the lanthanide series and two additional elements that share similar chemical properties. They are listed below in order of atomic number (Z): Scandium or Sc (21). Scandium, a silvery-white metal, is a non-lanthanide rare earth.his silver-white metal is one of the most reactive rare earth elements. It is used to make special optical glasses, including infrared absorbing glass, camera and telescope lenses, and can also be used to make steel more malleable. Other applications for lanthanum include wastewater treatment and petroleum refining.

Lawrencium Lawrencium is a synthetic chemical element with chemical symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements.ecause the name lawrencium had been in use for a long time by this point, it was retained by IUPAC, and in August 1997, the International Union of Pure and Applied Chemistry (IUPAC) ratified the name lawrencium and the symbol Lr during a meeting in Geneva.

Iridium Element Facts A very hard, brittle, silvery-white transition metal of the platinum group, iridium is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that iridium is denser.

Molybdenum Molybdenum does not occur naturally as a free metal on Earth, but rather in various oxidation states in minerals. The free element, which is a silvery metal with a gray cast, has the sixth-highest melting point of any element.olybdenum is also used in steel alloys for its high corrosion resistance and weldability. Molybdenum contributes further corrosion resistance to type-300 stainless steels (specifically type-316) and especially so in the so-called super austenitic stainless steels (such as alloy AL-6XN, 254SMO or 1925hMo).

LANTHANUM Overview. Lanthanum is the third element in Row 6 of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Lanthanum is a transition element in Group 3 (IIIB) of the periodic table. Lanthanum's position makes it one of the transition metals. The transition metals are found in the center of the periodic table, in Groups 3 through 12. Lanthanum can also be classified as a rare earth element.

Borides The diborides (MeB2) are used most widely in engineering. The most important indicator of these materials is the change in their basic properties with temperature (see Figures 1, 2, and 3). The most important physical properties of some borides of refractory metals are shown in Table 1. A large group is formed by borides of rare-earth metals-the lantha-nides and scandium and yttrium, whose properties are similar to those of the lanthanides. The most interesting in this group are the hexaborides (MeB6).

Erbium: the essentials Pure erbium metal is soft and malleable and has a bright, silvery, metallic lustre. As with other rare-earth metals, its properties depend to a certain extent on impurities present. The metal is fairly stable in air and does not oxidise as rapidly as some of the other rare-earth metals.

Yttrium Yttria-- earth containing yttrium-- was discovered by Gadolin in 1794. Ytterby is the site of a quarry which yielded many unusual minerals containing rare earths and other elements. This small town, near Stockholm, bears the honor of giving names to erbium, terbium, and ytterbium as well as yttrium.

- Terbium is classified as a rare earth element. The term is misleading because terbium is more common than metals such as silver and mercury. The name rare earth meant something else to early chemists. It was used because the rare earth elements were very difficult to separate from each other.
