Introduction of thortveitite ore

Thortveitite ore     Scandium has the properties of low relative density (almost equal to aluminum) and high melting point. Scandium nitride (ScN) has a melting point of 2900C and high conductivity, making it widely used in the electronics and radio industries. Scandium is one of the materials fo... Read More

Extraction methods of scandium

Extraction methods of scandium     For a considerable period of time after its discovery, the use of scandium was not demonstrated due to its difficulty in production. With the increasing improvement of rare earth element separation methods, there is now a mature process flow for purifying scandi... Read More

The main uses of scandium

The main uses of scandium    The use of scandium (as the main working substance, not for doping) is concentrated in a very bright direction, and it is not an exaggeration to call it the Son of Light.   1. Scandium sodium lamp The first magic weapon of scandium is called scandium sodium lamp, whic... Read More

Rare Earth Elements | Lutetium (Lu)

In 1907, Welsbach and G. Urban conducted their own research and discovered a new element from “ytterbium” using different separation methods. Welsbach named this element Cp (Cassiope ium), while G. Urban named it Lu (Lutetium) based on Paris’ old name lutece. Later, it was disc... Read More

Rare earth element | Ytterbium (Yb)

In 1878, Jean Charles and G.de Marignac discovered a new rare earth element in “erbium”, named Ytterbium by Ytterby. The main uses of ytterbium are as follows: (1) Used as a thermal shielding coating material. Ytterbium can significantly improve the corrosion resistance of electrodep... Read More

Rare earth element | Thulium (Tm)

  Thulium  element was discovered by Cliff in Sweden in 1879 and named Thulium after the old name Thule in Scandinavia. The main uses of thulium are as follows.   (1) Thulium is used as a light and light medical radiation source. After being irradiated in the second new class after the... Read More

Rare earth element | erbium (Er)

In 1843, Mossander of Sweden discovered the element erbium. The optical properties of erbium are very prominent, and the light emission at 1550mm of EP+, which has always been a concern, has special significance because this wavelength is precisely located at the lowest perturbation of the optic...

Rare earth element | cerium (Ce)

The element ‘cerium’ was discovered and named in 1803 by German Klaus, Swedes Usbzil, and Hessenger, in memory of the asteroid Ceres discovered in 1801.   The application of cerium can be mainly summarized in the following aspects.   (1) Cerium, as a glass additive, can abs... Read More

Rare earth element | Holmium (Ho)

In the second half of the 19th century, the discovery of spectroscopic analysis and the publication of periodic tables, coupled with the advancement of electrochemical separation processes for rare earth elements, further promoted the discovery of new rare earth elements. In 1879, Cliff, a Swede... Read More

Rare earth element | Dysprosium（Dy）

In 1886, the Frenchman Boise Baudelaire successfully separated holmium into two elements, one still known as holmium, and the other named dysrosium based on the meaning of “difficult to obtain” from holmium (Figures 4-11). Dysprosium is currently playing an increasingly important rol... Read More

Rare earth element | Terbium (Tb)

In 1843, Karl G. Mosander of Sweden discovered the element terbium through his research on yttrium earth. The application of terbium mostly involves high-tech fields, which are technology intensive and knowledge intensive cutting-edge projects, as well as projects with significant economic benef...

Rare earth element | gadolinium (Gd)

In 1880, G.de Marignac of Switzerland separated “samarium” into two elements, one of which was confirmed by Solit to be samarium and the other element was confirmed by Bois Baudelaire’s research. In 1886, Marignac named this new element gadolinium in honor of the Dutch chemist ... Read More
