Magical Rare Earth Element: Terbium
Terbium belongs to the category of heavy rare earths, with a low abundance in the Earth’s crust at only 1.1 ppm. Terbium oxide accounts for less than 0.01% of the total rare earths. Even in the high yttrium ion type heavy rare earth ore with the highest content of terbium, the terbium conte...Read more -
Magical Rare Earth Element: Cerium
Cerium is the undisputed ‘big brother’ in the large family of rare earth elements. Firstly, the total abundance of rare earths in the crust is 238ppm, with cerium at 68ppm, accounting for 28% of the total rare earth composition and ranking first; Secondly, cerium is the second rare ea...Read more -
Magical Rare Earth Elements Scandium
Scandium, with element symbol Sc and Atomic number of 21, is easily soluble in water, can interact with hot water, and easily darkens in the air. Its main valence is+3. It is often mixed with gadolinium, erbium, and other elements, with a low yield and a content of approximately 0.0005% in the cr...Read more -
The magical rare earth element europium
Europium, the symbol is Eu, and the Atomic number is 63. As a typical member of Lanthanide, europium usually has+3 valence, but oxygen+2 valence is also common. There are fewer compounds of europium with a valence state of+2. Compared with other heavy metals, europium has no significant biologica...Read more -
Magical Rare Earth Element: Lutetium
Lutetium is a rare rare earth element with high prices, minimal reserves, and limited uses. It is soft and soluble in dilute acids, and can slowly react with water. The naturally occurring isotopes include 175Lu and a half-life of 2.1 × 10 ^ 10 years old β Emitter 176Lu. It is made by reducing Lu...Read more -
Magical Rare Earth Element – Praseodymium
Praseodymium is the third most abundant lanthanide element in the periodic table of chemical elements, with an abundance of 9.5 ppm in the crust, only lower than cerium, yttrium, lanthanum, and scandium. It is the fifth most abundant element in rare earths. But just like his name, praseodymium is...Read more -
Barium in Bolognite
arium, element 56 of the periodic table. Barium hydroxide, barium chloride, barium sulfate… are very common reagents in high school textbooks. In 1602, western alchemists discovered the Bologna stone (also called “sunstone”) that can emit light. This kind of ore has small lum...Read more -
What is Cerium Oxide？
Cerium oxide is an inorganic substance with the chemical formula CeO2, light yellow or yellowish brown auxiliary powder. Density 7.13g/cm3, melting point 2397°C, insoluble in water and alkali, slightly soluble in acid. At a temperature of 2000°C and a pressure of 15MPa, hydrogen can be used to re...Read more -
Application of nano cerium oxide in polymer
Nano-ceria improves ultraviolet aging resistance of polymer. The 4f electronic structure of nano-CeO2 is very sensitive to light absorption, and the absorption band is mostly in the ultraviolet region (200-400nm), which has no characteristic absorption to visible light and good transmittance. Ord...Read more -
