Process Flow Diagram


Yttrium oxyfluoride (YOF3) is a transparent white or light yellow crystal with high refractive index, low light absorption, high chemical stability and high heat resistance. These characteristics make yttrium oxyfluoride has a wide range of applications in the field of optics, such as the manufacture of high refractive index optical glass, optical lenses, optical fibers and so on. In addition, yttrium oxyfluoride can also be used to manufacture rare earth laser crystals and other optical devices.


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