Synthesis, morphology and structure of the dense (Y1-xEux)2O3 spherical shape particles.

The method to decrease of the porosity (densification) of crystalline spherical particles of the solid substitution solution, obtained by the method of precipitation from aqueous solution followed by low temperature crystallization of the amorphous intermediate product was proposed. The comparative analysis of morphology and structure of the particles before and after densification have been carried. It has been established that porosity of (Y1-xEux)2O3 particles has decreased 5 times compared to their initial state. It has been shown that densification process of the (Y1-xEux)2O3 spherical particles changes their morphology and structure: the size of the crystals doubles, the number and area of crystalline boundaries decrease, the intercrystalline spaces, which forming pores, are almost absent.
