DOMADIA LUTETIUM 99.9% purity in Any Shape and Size.
Pure metallic lutetium has been isolated only in recent years and is one of the more 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. It is a rare earth metal and perhaps the most expensive of all rare elements. It is found in small amounts with all rare earth metals, and is very difficult to separate from other rare elements.

Lanthanum, atomic no.: 57, symbol as La, weight at 138.91, is the first element in the rare earth or Lanthanide series. It is the model for all the other trivalent rare earths. After Cerium, it is the second most abundant of the rare earths. Lanthanum-rich Lanthanide compounds have been used extensively for cracking reactions in FCC catalysts, especially to manufacture high-octane gasoline from heavy crude oil. Lanthanum-Rich Rare Earth metals play the important roles in hydrogen storage batteries. It is utilized in green phosphors based on the phosphate (La0.4Ce0.45Tb0.15)PO4. It is utilized in laser crystals based on the Yttrium-Lanthanum-Fluoride (YLF) composition. Lanthanum Fluoride is used in phosphor lamp coatings. Lanthanum Fluoride (LaF3) is an essential component of a heavy Fluoride glass named ZBLAN. This glass has superior transmittance in the infrared range and is therefore used for fiber-optical communication systems. Lanthanum Oxide and the Boride are used in electronic vacuum tubes as hot cathode materials with strong emissivity of electrons. Crystals of LaB6 are used in high brightness, extended life, thermionic electron emission sources for electron microscopes, and Hall effect thrusters. Lanthanum(III) Oxide (La2O3) improves the alkali resistance of glass, and is used in making special optical glasses, such as infrared-absorbing glass, as well as camera and telescope lenses, because of the high refractive index and low dispersion of rare-earth glasses. Lanthanum Oxide is also used as a grain growth additive during the liquid phase sintering of Silicon Nitride and Zirconium Diboride.

Promethium: the essentials Great care is required while handling promethium as a consequence of its radioactivity. Promethium salts luminesce in the dark with a pale blue or greenish glow, due to their high radioactivity. Ion-exchange methods led to the preparation of about 10 g of promethium from atomic reactor fuel processing wastes in early 1963. Little is yet generally known about the properties of metallic promethium. More than 30 promethium compounds have been prepared. Promethium is a rare earth metal. It appears that there is no known Pm existing in the earth's crust.

The metal is lustrous, bluish white, extremely hard and brittle even at high temperatures. It has the highest melting point and lowest vapour pressure of the platinum group metals. The metal is very difficult to fabricate but can be sintered in a hydrogen atmosphere at a temperature around 2000°C.

The solid metal is not affected by air at room temperature but the powdered or spongy metal slowly gives off osmium tetroxide, which is a powerful oxidising agent, and has a strong smell. The tetroxide is highly toxic and boils at 130°C.

The metal has been used to produce very hard alloys with other platinum group metals, for fountain pen tips, for instrument pivots, for gramophone needles and electrical contacts.

It is used in some catalytic applications and has an interesting chemistry based on cluster compounds.
