Europium Oxide CAS#1308-96-9

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Europium Oxide which has developed particularly rapidly in recent years. Do you know about Europium Oxide?

The official answer: The academic formula Is Eu2O3. Molecular weight 351.92. Light rose red powder, hygroscopic, due to the preparation of different colors also have a little difference. Depending on the heating temperature, two variants of the quasi-tripartite crystal system and the isoaxial crystal system can be obtained, and the crystal structure of the latter is the same as scandium oxide. The relative density is 7.42, and the melting point is 2330 °C. Insoluble in water, it can be dissolved in inorganic acid to generate a trivalent osmium solution of the corresponding acid, and it is also soluble in Chemicalbook in formic acid and acetic acid, which can absorb carbon dioxide from the air to form carbonate. The main uses of europium oxide are as a red phosphor activator for color television sets, phosphors for high-pressure mercury lamps, and excited phosphors for new X-ray medical diagnostic systems. Europium oxide can also be used to make colored lenses and optical filters for magnetic bubble storage devices, nuclear reactor control rods, shielding materials and structural materials.
