Highly dense, spherical yttria (Y 2 O 3 ) and erbia (Er 2 O 3 ) particles were synthesized from their corresponding metal-ethylenediaminetetraacetic (EDTA) complexes. The EDTA·Y·H and EDTA·Er·H complexes were prepared in powdered form. These complexes were used as the staring materials for synthesis of the Y 2 O 3 and Er 2 O 3 particles. The particles were synthesized using an H 2 -O 2 flame produced with a commercial flame spray apparatus. Crystalline structure, surface and cross-sectional morphologies, and elemental distribution of the synthesized particles were investigated. It was confirmed that the crystalline phases of the Y 2 O 3 and Er 2 O 3 particles were homogeneous. In addition, the elemental distribution of the particles was uniform. These results indicate that dense, spherical particles of Y 2 O 3 and Er 2 O 3 have been synthesized with EDTA·Y·H and EDTA·Er·H complexes, respectively.
