Samarium is a silvery-white metal that has a characteristic glow, it is stable when exposed to air. In the atmosphere, it is relatively ductile, malleable and soft. It forms part of the external transition metals and belongs to the group of lanthanides. It was discovered in 1879 by the French chemist Paul-Emile Lecoq de Boisbaudran who isolated the metal from the mineral Samarsquita, after having been observed through for spectroscopy by Swiss chemical Marignac in didymium. It was named af …

Terbium was discovered in 1843 by C. Mosander. It is named for Ytterby, a Swedish town where the rare earth oxides were found. It is silver-gray metal, malleable, ductile and soft enough to be cut with a knife. The technical importance of terbium is found in various applications in catalysis and laser technology. In this article, we will discuss the history, properties, and applications of Terbium.Terbium is a rare earth element and its symbol is Tb, a white metallic solid and silver luste …

The Rare Earth elements are very special and are used in most modern technologies. The Rare Earth elements include as many as 17 chemical elements, which in recent years have become very precious and refined. In many productions (magnets, catalysts, displays) the Rare Earth elements are indispensable. The Rare Earth elements are these: dysprosium (Dy), cerium (Ce), erbium (Er), gadolinium (Gd), europium (Eu), holmium (Ho), Lutetium (Lu), lanthanum (La) …

Europium micron powder is a chemical component with the symbol of Eu and atomic number 63. It is a silvery-white lanthanide and belongs to rare earth metals. In 1896, Eugene-Antole Demarcay discovered a suspicious element in the mixture of the elements of samarium and gadolinium, which did not belong to those elements. This created the suspicion of the existence of europium. The world reserves of europium powder are around 150,000 tonnes and the world production is about 100 tonnes per yea …
