Abstract
The synthesis of the dysprosium oxide by using the anion exchange precipitation of the precursor from the nitrate solutions by strong base anion resin AV-17-8 followed by heat treatment at 850 ° C. It is found that is necessary to carry out the synthesis using AB-17-8 in CO3-form. The products have been characterized by IR spectroscopy, XRD, TEM. It was determined that the resulting product is Dy2O3, containing no impurities of other phases, and the particles have a size of 20-30 nm.
