Application
*cerium fluoride cef3, is the important raw material for polishing powder, special glass, metallurgical applications. It is the most efficient glass polishing agent for precision optical polishing.
*It is also used to decolorize glass by keeping iron in its ferrous state. In steel manufacturing, it is used to remove free Oxygen and Sulfur by forming stable oxysulfides and by tying up undesirable trace elements, such as lead and antimony.
Packing
In sealed double polyethylene bags. The bags are packed in steel drums containing 50 Kgs net each.
Others
Specification is adjustable as per user' s special requirement
