摘要
报道了一种液相控制沉淀与分解制备Co3O4超微粉的方法.研究表明,采用液相沉淀控制技术,无需引入高分子保护剂,同样可以制备出晶粒细小、粒度分布均匀、无团聚的高质量Co3O4超微粉.该法工艺简单、成本低、产率高.
A precipitation method to prepare Co_3O_4 ultrafines was reported.The results shown that non-agglomerated and well dispersed Co_3O_4 ultrafine particles with the averages size of 30?nm were successfully prepared only by a liquid control precipitation technique without adding any polymer protecting agent.The precipitation method possesses the advantage of simple processing, cheap cost and high yield.
