Process Flow Diagram



Europium Oxide, also called Europia, is used as a phosphor activator, color cathode-ray tubes and liquid-crystal displays used in computer monitors and televisions employ Europium Oxide as the red phosphor; no substitute is known. Europium Oxide (Eu2O3) is widely used as a red phosphor in television sets and fluorescent lamps, and as an activator for Yttrium-based phosphors. Europium Oxide is also applied in speciality plastic for laser material.



In sealed double polyethylene bags. The bags are packed in steel drums containing 25 or 50 Kgs net each.


Specification is adjustable as per user' s special requirement.
