Is europium oxide toxic?
What is Europium oxide?
Europium oxide is an inorganic compound with a light pink powder. Insoluble in water but soluble in acid. It can be volatilized with steam, alkaline, toxic, irritating to eyes, respiratory tract, and skin, absorbing carbon dioxide in the air and generating water-soluble salts with inorganic acids. Europium (III) oxide Eu2O3 is a compound of europium and oxygen. Europium oxide is widely used as red or blue phosphors for television sets and fluorescent lamps and as an activator of yttrium-based phosphors. It is also an auxiliary agent for the production of fluorescent glass. Europium fluorescence is used as an anti-counterfeiting phosphor on euro banknotes. Europium oxide has two common structures: monoclinic and cubic structures similar to manganese (III) oxide. Europium oxide can react with acids to form corresponding europium (III) salts.

Europium oxide is a pink powder. The relative density is 7.42g/cm3. The melting point is 2350℃. Insoluble in water but soluble in acid. It can be volatilized with steam, alkaline, toxic, irritating to eyes, respiratory tract, and skin, absorbing carbon dioxide in the air and generating water-soluble salts with inorganic acids.
production of Europium oxide
The extraction method takes rare earth chloride solution obtained by treating monazite or mixed rare earth ore as raw material. Using P204- kerosene -HCL-ReCl3 system for extraction, firstly, neodymium and samarium are grouped, the raffinate is used to extract rare light earth, samarium and rare heavy earth is extracted into the organic phase, and then the medium rare earth is back-extracted with 2.0mg/L HCl to obtain a medium rare earth samarium concentrate, which is reduced by zinc powder, europium is extracted by alkaline method, precipitated by oxalic acid, separated and dried.
Toxicity of Europium Oxide
Salts of rare earth elements can reduce the content of blood proenzyme, inactivate it, inhibit the production of thromboplastin, precipitate fibrinogen, and catalyze the decomposition of phosphate compounds. The toxicity of rare earth elements decreases with the increase in atomic weight. When working, you need to wear a gas mask. If there is radioactivity, you should take special protection and prevent dust from scattering.
Price of Europium oxide
Europium oxide particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Europium oxide. A large amount of large amount will be lower. The price of Europium oxide can be found on our company's official website.
