High Purity 99.999% Europium Oxide Eu2O3 CAS 1308-96-9 For Color TV Phosphor

Europium oxide is an inorganic compound that is white to a pale pink powder. It has a high melting point (2350 ° C) and is insoluble in water, but soluble in acid. Europium oxide has important applications in many fields: as an activator of phosphors for color television sets and high-pressure mercury lamps, it can emit bright red fluorescence; In the field of optics, for the manufacture of colored lenses and optical filters; In the nuclear industry, as a neutron absorber and control material; At the same time, it is also used in the preparation of dyes, rubber vulcanization accelerator and other chemical raw materials. However, europium oxide is toxic and requires protective measures when handled.

Name: Europium oxide

CAS: 1308-96-9

Molecular formula: Eu2O3

Molecular weight: 351.93

Description

Non-rare earth impurities such as iron, copper, zinc and calcium in Europium oxide will reduce the quality of phosphors. They are usually removed by sulfide precipitation or amine extraction in the production process, and Europium oxalate is precipitated by oxalic acid. Europium oxalate was calcined to produce Europium oxide of fluorescence grade.
