Process Flow Diagram


Erbium Oxide (Er2O3) Xinkang Deposition specializes in producing high purity evaporation materials with high quality for use in semiconductor, chemical vapor deposition (CVD) and physical vapor deposition (PVD) display and optical applications.

Erbium Oxide is an important colourant in glasses and porcelain enamel glazes. High purity Erbium Oxide are widely applied as dopant in making optical fibre and amplifier.

Erbium Oxide for making red fluorescent powder for color TVs. rare earth trichromatic power-saving lamps and long persistence phosphor etc.

The unique synergy between our engineering, manufacturing and analytical teams has allowed us to produce industry leading evaporation materials.



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.
