Rare Earth Metals
Rare earth metals are a group of 17 chemical elements, also known as lanthanides, found in the Earths crust. They include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, a......
Rare earth polishing powder
Introduction
Rare earth polishing powder is a basic material used in many industries, such as automobiles, lighting, electronics, medicine, etc. It is a kind of white powder made of rare earth elements. It has the characteristics of high gloss, high luster, wear-resistant, smooth surface, high t......
Rare earth phosphor
Rare earth phosphors are phosphors made of rare earth ions activated in an appropriate matrix. Rare earth phosphors usually emit visible light but can also emit up to ultraviolet (UV) light. The rare earths used in phosphors are lanthanides and include elements such as Cerium, Gadolinium, Ytterbiu......
rare light metal
Rare earths are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides, as well as scandium and yttrium. Rare earths are present in the earth’s crust but are not found in large enough concentrations that they can be economically extracted.
They form a c......
Preparation of Rare Earth Metals by Molten Salt Electrolysis
Production of Rare Earth Metals by Fused Salt Electrolysis
Rare earth metals in their pure elemental form are not found in nature, thus there is a need for an efficient method for producing them. Fused salt electrolysis, where a mixture of molten salts and rare earth metals are used in electroche......

RARE EARTH METALS
Rare earth metals are a set of seventeen chemical elements in the periodic table, specifically the fifteen lanthanides plus scandium and yttrium. They are also called lanthanoids, because the most abundant members of the group are sometimes referred to collectively as “the lanth......

Rare Earth Metals: Extracting and Uses
Rare earth metals are a group of 17 metals that are typically found together in the form of minerals, though some are present in seawater and can be extracted from this source. The elements that comprise the group are cerium, dysprosium, erbium, europium, g......
Rubidium and Cesium Extraction by Step Precipitation
The Separation of Ruthenium and Cesium by Stepwise Precipitation
Stepwise precipitation is a powerful method of separation used mainly in the field of analytical chemistry. It is often used to separate and quantify components of mixtures, including elements of different atomic masses. The method ......
Chromatographic separation of rare earth elements
Rare-earth elements (REEs) are a group of 17 chemical elements in the periodic table, namely scandium (Sc), yttrium (Y), and 15 lanthanides. The term “rare earths” name was first used in 1827 by Swedish chemist, Carl Axel Arrhenius, but the elements themselves were not discovered until late 18-1......
