| Abstract: | A liquid\|control\|precipitation(LCP) method to prepare Co\-3O\-4 ultrafines was \{reported\} in this paper. The results shown that non\|agglomerated and well dispersed Co\-3O\-4 \{ultrafine\} 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. |
