Name: Nano gadolinium oxide CAS: 12064-62-9
Molecular formula: Gd2O3 Molecular weight: 362.5
Description: Nano gadolinium oxide is a white amorphous powder, insoluble in water and soluble in acid. It is easy to absorb water and carbon dioxide in the air. When reacting with ammonia, gadolinium hydrate is precipitated. The preparation method of nanometer gadolinium oxide is that gadolinium oxide precursor is prepared with GdCl3 as raw material and polyvinyl alcohol as dispersant by ammonium bicarbonate precipitation process, then methanol is added, and it is heated to decompose, the gadolinium oxide Gd2O3 obtained is crushed and screened to obtain nanometer gadolinium oxide.

Used: Used in the manufacture of NMR contrast agents and yttrium aluminum and yttrium iron garnet admixtures. The main uses of nano gadolinium oxide are as follows: 1. Its water-soluble paramagnetic complex can improve the MRI signal of human body in medical treatment. 2. Its sulfur oxide can be used as a special brightness oscilloscope and X-ray fluorescence intensifying screen. 3. Nano gadolinium oxide in nano gadolinium oxide gallium garnet is an ideal single substrate for bubble memory memory memory. 4. It can be used as solid-state magnetic cooling medium. 5. It is used as an inhibitor to control the chain reaction level of nuclear power plant to ensure the safety of nuclear reaction. In addition, the use of nano gadolinium oxide and nano lanthanum oxide can help to change the glass transition region and improve the thermal stability of glass.
