Process Flow Diagram


Terbium oxide is used in the following applications:

1.Electronics industry: Terbium oxide can be used in the manufacture of electronic devices such as capacitors, resistors and inductors.

2.Optical field: Terbium oxide is characterized by high refractive index and low phonon energy, making it important in the manufacture of optical films and optical devices.

3.Magnetic materials: Terbium oxide has excellent magnetic properties and can be used to manufacture permanent magnetic materials and magnetostrictive materials.

4.Biomedicine: Terbium oxide can also be used in the biomedical field, such as bio-imaging agents, drug carriers and therapeutic agents.



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.
