The Famous Twin Rare Earth Element Mystery – The Powerful “Neodymium” Magnet

Knowledge Column, Product Applications / By

Introduction Neodymium was discovered in 1885 by Austrian chemist C. A. von Welsbach in Vienna. Interestingly, the name “Neodymium” comes from the Greek words “neos” (νέος), meaning “new,” and “didymos” (διδύμος), meaning “twin.” Naturally occurring neodymium consists of seven isotopes: stable isotopes 143Nd, 145Nd, 146Nd, 148Nd, the most common 142Nd, and long-lived primordial radioactive isotopes …

“Erbium” seems to have a knack for separation, as it has given rise to several rare earth elements

Knowledge Column, Product Applications / By

In a previous article, we mentioned the rare earth element “Terbium.” Its sibling elements, discovered in the same year, include “Erbium.” Initially, terbium oxide and erbium oxide were confused with each other, and it wasn’t until after 1860 that this was corrected. Both Er and Tb were isolated from gadolinite, yet their oxides differ in …

The Rare Earth Triplets—Terbium, the Unfortunate Victim

Knowledge Column, Product Applications / By

Previously, we discussed how “Yttrium” was discovered in a mine near the village of Ytterby in Sweden. Interestingly, there are three other elements that, much like triplets, have similar names and are often confused: Erbium (Er), Terbium (Tb), and Ytterbium (Yb). All of these were also discovered in the same area. In the lanthanide family, …

The Head of the Lanthanide Family — Lanthanum

Knowledge Column, Product Applications / By

When discussing rare earth elements, we cannot overlook the large group of lanthanides, one of the most important categories in the periodic table.Most lanthanide elements are found in monazite and bastnäsite, and they are typically mixed together in stable proportions (with lanthanum comprising 25-38%). These elements are separated from each other as oxides and are …

Yttrium Brought Back by Apollo from the Moon

Knowledge Column, Product Applications / By

Recently, the topic of superconductors has resurfaced in discussions, particularly with the idea that at low enough temperatures, certain materials exhibit zero electrical resistance—a phenomenon known as superconductivity. Introduction In 1986, scientists Muller and Bednorz at IBM’s laboratory in Switzerland discovered a series of ceramics that exhibited superconductivity at 35 K. The following year, scientists …

The Inseparable Relationship Between Diamonds and Superconductors

Knowledge Column, Product Applications / By

When discussing the connection between diamonds and superconductors, the most exciting topic is the superconductivity of diamonds. Under the right conditions, diamonds can exhibit superconducting properties, a discovery that has attracted significant attention in the scientific community and opened up new possibilities for superconducting technologies and applications. Initial Discovery of Diamond Superconductivity In 1991, scientists …

Raw Materials

Product Applications / By

Why are raw materials so important? The selection shapes the outcome. The quality of the raw materials you use directly affects the quality of the resulting products! Rare earth materials are not only known as the “vitamins of the semiconductor industry,” but with just a small amount added, they achieve the effect of “industrial vitamins” …
