Abstract: Aliquid-control-precipitation(LCP) method to prepare Co3O4ultrafines was reported in this paper. The results shown that non-agglomerated and well dispersed Co3O4ultrafine particles with the averages size of 9 nm were successfully prepared only by a liquid control precipitation technique without adding any polymer protecting agent. The LCP method possesses the advantage of simple processing, cheap cost and high yield.

Key words: Co3O4, Nanocrystalline, Liquid-control-precipitation
