Cerium is an iron-grey lustrous metal. It is malleable, and oxidises very readily at room temperature, especially in moist air. Except for europium, cerium is the most reactive of the rare-earth metals.
Dy Dysprosium Metal
99.99% sublimed
Dysprosium has a metallic, bright silver lustre. It is relatively stable in air at room temperature, but dissolves readily, with the evolution of hydrogen, in mineral acids. It is a rare earth metal found in minerals such as xenotime, monazite and bastnaesite. Dysprosium Metal is an important additive for NdFeB permanent magnets to raise the Curie temperature and improve temperature coefficiency
Er Erbium Metal
99.99% sublimed
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, mainly metallurgical uses; added to vanadium, for example, erbium lowers hardness and improves workability; also a few applications for nuclear industry.
Eu Europium Metal
99.99% sublimed
Europium is about as hard as lead and is quite ductile. It is the most reactive of the rare earth metals, quickly oxidising in air. Europium Metal, is very valuable material in control rods for nuclear reactors due to that it can absorb more neutrons than any other elements.

Indium is used in making bearing alloys, germanium transistors, rectifiers, thermistors, and photoconductors; and used in solders and etc.
La Lanthanum Metal
Lanthanum is one of the most reactive of the rare-earth metals. It oxidises rapidly when exposed to air. Cold water attacks lanthanum slowly, and hot water attacks it much more rapidly. The metal reacts directly with elemental carbon, nitrogen, boron, selenium, silicon, phosphorus, sulphur, and with halogens. It is a component of, misch metal. And Lanthanum Metal is the very important raw materials in producing Hydrogen Storage Alloys for NiMH batteries, and is also used to produce other pure Rare Earth metals and specialty alloys.
Lu Lutetium Metal
99.99% sublimed
Lutetium metal is silvery white and relatively stable in air; is the hardest metal of the rare-earths; used as important additive to some specialty alloy. The lutetium atom is the smallest among the lanthanide atoms, due to the lanthanide contraction, and as a result lutetium has the highest density, melting point, and hardness of the lanthanides.
Mo Molybdenum Metal
Molybdenum is a silvery-white, hard, transition metal; valuable alloying agent (contributes to the hardenability and toughness of quenched and tempered steels). Almost all ultra-high strength steels contain molybdenum in amounts from 0.25 to 8%; improves the strength of steel at high temperatures; electrodes for electrically heated glass furnaces.
Nd Neodymium Metal
Neodymium Metal is mainly used in manufacturing very powerful permanent magnets-Neodymium-Iron-Boron magnets, and also are applied in making specialty superalloy and sputtering targets. Neodymium is one of the more reactive rare-earth metals and quickly tarnishes in air, forming an oxide that spalls off and exposes the metal to further oxidation. It is one of the rare earth metals.
Nb Niobium Metal
Niobium is a shiny, white, soft, and ductile metal, and takes on a bluish tinge when exposed to air at room temperatures for a long time. It is a component of some stainless steels and also alloys with nonferrous metals. These alloys have good strength and other properties, and are used in pipeline construction. The metal has a low capture crosssection for thermal neutrons and so finds use in the nuclear industries.
