Process Flow Diagram


    Yttrium oxide nanoparticle is an air-stable, solid substance white in color. It is used in the field of material sciences, to make phosphors that are used in imparting the red color of the picture tubes in televisions. Another major use of the yttrium oxide nanoparticles is in inorganic synthesis. Yttrium belongs to Block D, Period 5 and oxygen belongs to the Block P, Period 2 in the periodic table.

    Given below are some of the chief applications of yttrium oxide nanoparticles.

    1. In the field of materials science these particles find a number of applications such as imparting colour to the television picture tubes. Also used in making of plasma and flat panel displays.

    2. Yttrium iron garnets which are derived from yttrium oxide are used as powerful microwave filters.

    3. Yttrium oxide is a vital starting point in inorganic synthesis of compounds.

    4. The property of red light emission is used in making fluorescent lamps.

    5. They are also used as additives in the coatings used in high-temperature applications, paints and plastics for guarding against UV degradation and also in making permanent magnets.In ultrafast sensors that are used in g-ray and x-rays.



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.
