Chemical Properties

grey powder

Physical properties

In the last (17th) position in the lanthanide series, lutetium is the heaviest and largestmolecule of all the rare-earths as well as the hardest and most corrosion-resistant. It has asilvery-white color and is somewhat stable under normal atmospheric conditions.
Its melting point is 1,663°C, its boiling point is 3,402°C, and its density is 9.84g/cm3.

Isotopes

There are a total of 59 isotopes of Lutetium. Only two of these are stable: Lu-175, which makes up 97.41% of all the natural abundance found on Earth. The otheris a long-lived radioisotope (Lu-176) with such a long half-life (4.00×10+10 years) thatit is considered stable: Lu-176 contributes 2.59% to the natural abundance of lutetium.

Origin of Name

Lutetium’s name is derived from the ancient Latin name for Paris, France: Lutecia.

Occurrence

Lutetium is the 60th most abundant element on Earth, and it ranks 15th in the abundanceof the rare-earths. It is one of the rarest of the lanthanide series. It is found in monazite sand(India, Australia, Brazil, South Africa, and Florida), which contains small amounts of all therare-earths. Lutetium is found in the concentration of about 0.0001% in monazite. It is difficultto separate it from other rare-earths by the ion-exchange process. In the pure metallicform, lutetium is difficult to prepare, which makes is very expensive.

Characteristics

Lutetium has had a number of different names over the years. At one time or another,it was called neoytterbium, lutecium, lutetia, lutetium, and cassiopium. Some scientists inGermany still refer to it as cassiopium.
Lutetium reacts slowly with water and is soluble in weak acids. Its crystals exhibit strongmagnetic properties, which are important to the study of magnetism.

History

In 1907, Urbain described a process by which Marignac’s ytterbium (1879) could be separated into the two elements, ytterbium (neoytterbium) and lutetium. These elements were identical with “aldebaranium” and “cassiopeium,” independently discovered by von Welsbach about the same time. Charles James of the University of New Hampshire also independently prepared the very pure oxide, lutecia, at this time. The spelling of the element was changed from lutecium to lutetium in 1949. Lutetium occurs in very small amounts in nearly all minerals containing yttrium, and is present in monazite to the extent of about 0.003%, which is a commercial source. The pure metal has been isolated only in recent years and is one of the most difficult to prepare. It can be prepared by the reduction of anhydrous LuCl3 or LuF3 by an alkali or alkaline earth metal. The metal is silvery white and relatively stable in air. While new techniques, including ion-exchange reactions, have been developed to separate the various rare-earth elements, lutetium is still the most costly of all rare earths. It is priced at about $100/g (99.9%). 176Lu occurs naturally (97.41%) with 175Lu (2.59%), which is radioactive with a very long half-life of about 4 × 1010 years. Lutetium has 50 isotopes and isomers that are now recognized. Stable lutetium nuclides, which emit pure beta radiation after thermal neutron activation, can be used as catalysts in cracking, alkylation, hydrogenation, and polymerization. Virtually no other commercial uses have been found yet for lutetium. While lutetium, like other rare-earth metals, is thought to have a low toxicity rating, it should be handled with care until more information is available.

Uses

Lutetium is the last member of the rare earth series. Unlike most rare earths it lacks a magnetic moment. It also has the smallest metallic radius of any rare earth. It is perhaps the least naturally abundant of the Lanthanides. It is the ideal host for x-ray phosphors because it produces the densest known white material, Lutetium Tantalate (LuTaO4). It is utilized as a dopant in matching lattice parameters of certain substrate garnet crystals, such as Indium-Gallium-Garnet (IGG) crystals due its lack of a magnetic moment.
Lutetium isotopes can data the age of meteorites and are used to target tumors experimentally. Stable lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications.
Lutetium Metal, is the hardest metal of the rare-earths, used as important additive to some specialty alloy. Stable Lutetium can be used as catalysts in petroleum cracking in refineries and can also be used in alkylation, hydrogenation, and polymerization applications. Lutetium is used as a phosphor in LED light bulbs.

Uses

Because lutetium is difficult to prepare on a large scale, its practical uses are limited. Someof its radioisotopes are used as catalysts in the cracking (refining) process of crude oil, whichproduces lighter fractions such as diesel fuel and gasoline. It can also be used as a catalyst tospeed up the reaction in some hydrogenation processes wherein hydrogen is added to vegetableoils to make more solid products. Some of its isotopes have been used to determine theage of meteorites.

Definition

A silvery element of the lanthanoid series of metals. It occurs in association with other lanthanoids. Lutetium is a very rare lanthanoid and has few uses. Symbol: Lu; m.p. 1663°C; b.p. 3395°C; r.d. 9.84 (25°C); p.n. 71; r.a.m. 174.967.

Definition

lutetium: Symbol Lu. A silvery metallic element belonging to thelanthanoids; a.n. 71; r.a.m. 174.97;r.d. 9.8404 (20°C); m.p. 1663°C; b.p.3402°C. Lutetium is the least abundantof the elements and the little quantities that are available have been obtained by processing other metals. There are two natural isotopes,lutetium–175 (stable) andlutetium–176 (half-life 2.2×1010years). The element is used as a catalyst.It was first identified by GergesUrbain (1872–1938) in 1907.

Hazard

Lutetium fluoride is a skin irritant, and its fumes are toxic if inhaled. The dust and powderof the oxides of some rare-earths, including lutetium, are toxic if inhaled or ingested.
