Thulium is a chemical element belonging to the lanthanide series of rare-earth metals. It is the 13th element and the third to the last in the series. The element has the atomic number 69 and is known by the symbol, Tm. Thulium has variable oxidation states, but the most common oxidation state is +3, which...Continue Reading

Rare Earth Terbium – Description Terbium, the 65th element of the periodic table, is a rare earth metal belonging to the lanthanide series. Although the lanthanides have been described as a boring group of elements, each of them has its own unique properties and uses. Terbium, though not as popular as Neodymium, Ytterbium, or Samarium,...Continue Reading

Samarium is a yellowish rare earth element belonging to the lanthanide series of metals on the periodic table. Although samarium is similar in appearance and properties to most other metals, it has relatively fewer uses. A notable application of samarium is in the manufacture of very powerful magnets. Compounds of samarium are also used in...Continue Reading

What is Magnetron Sputtering? Sputtering is the process in which the atoms or molecules of a material are ejected from a target by bombarding the target with high-energy particles. This is called DC sputtering or diode sputtering. A major disadvantage of such a sputtering technique is that it has very low deposition rates and involves...Continue Reading

The magnetron sputtering system has been in use for several decades now. Even recently, there have been advancements that have improved the performance of the sputtering system in general. For instance, the closed-field unbalanced magnetron sputtering technique has now been developed so that it can be routinely used to deposit high-quality coatings of an extensive...Continue Reading

Introduction to Rare Earth Element Promethium Promethium is an interesting element when you consider its physical and chemical properties, as well as its occurrence and production. It is an extremely rare metal, with only about 500–600 grams naturally occurring in the earth’s crust at any given time. However, it is not stable and therefore undergoes...Continue Reading

Neodymium is a metal with atomic number 60, belonging to the lanthanide series of metals on the periodic table. The name Neodymium is derived from the Greek word ‘neos didymos’, which means new twin. Neodymium is a rare-earth metal that is used with iron and boron to create powerful permanent magnets, which are called NdFeB...Continue Reading

Introduction: What is Lutetium? Lutetium is a silvery-white rare-earth metal. It is the last element in the lanthanide series. Lutetium was independently found by three scientists (Georges Urbain, Baron Carl Auer von Welsbach, and Charles James) as an impurity in the mineral ytterbia, which was previously thought to consist only of ytterbium. It has an...Continue Reading

Introduction Lanthanum is a rare-earth element with a silvery-white appearance. It is represented as La and is number one on the lanthanide series. Lanthanum is described as the second most reactive element in the lanthanide series. Contrary to its classification as a rare-earth element, lanthanum is the 28th most abundant element. It is also the...Continue Reading
