Abstract: This paper describes the preparation of monodispersed sol of zirconium basic carbonate consisting of particles with diameter less than 0.6 μm by aging Zr(Ⅳ) solution at elevated temperature in the presence of urea and glycerol. The composition of the monodispersed particles has primarily been determined by the IR spectra and the weight-loss of the particles on calcination. The monodispersed particles of ZrO_2 were obtained by calcination of the monodispersed particles separated from the sol at 850 ℃ for 2 h.

Key words: Monodispersed colloid, Zirconium basic carbonate, Zirconium oxide
