Monodispersed colloidal YOHCO_3·H_2O and Y_2O_3 systems consisting of spherical particles of narrow size distribution were obtained. The formation of those monodispersed colloidal systems was primarily investigated by using the techniques including transmision and scanning electron mieroseopy,IR spectroscopy and electrical conductivity. The change of electrical conductivity in the course of aging YCl_3 solution with urea revealed that the slow decomposition of urea and release of CO_3~(2-) at elevated temperature controlled the generation of pricipitation phase and provided necessary condition for formation of the monodispersed system.
The transformation of calcining monodispersed powders of YOHCO_3·H_2O was observed through SEM. During the process of calcining YOHCO_3·H_2O at 850 ℃, the powders were melten first before formation of monodispersed spheres of Y_2O_3.
