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.
