摘　　要：酞菁钴 (Co Pc)和羰基铁的原位复合 ,制备出稳定的铁 /酞菁钴复合粒子。XRD、SEM、TG和 DTA的表征表明 :复合粒子的结构、形态和组成与采用的制备方式有关。分解时 ,羰基铁的浓度越低 ,复合粒子的粒径越小。Co Pc和羰基铁的混合液回流 ,Co Pc用量不小于 6.7%(质量分数 ) ,可得以铁为主、粒径 1 .2 0 μm± 0 .1 0 μm、密度 3.664g/cm3、Co Pc完全包覆的铁 /酞菁钴复合粒子。 Co Pc的完全包覆提高了复合粒子中超微铁的抗氧化性。The carbonyl iron/cobalt phthalocyanine composites were obtained while the solution of carbonyl iron and cobalt phthalocyanine (CoPc) mixing into DMF was backflowing for 3 hours at 114 ~120℃ composite in situ . Composite particles were analyzed using XRD, SEM, TG and DTA. The result shows that the composition and structure of the Fe/CoPc composites are different using various methods of synthesis. The lower the concentration of carbonyl iron decomposing and forming Fe particles, the smaller the average diameter of composites. The surface of the Fe/CoPc composites is covered completely by CoPc, they are almost regular spherical shape and their diameter is of 1.20μm±0.10 μm when the mass content of CoPc in the backflow solution is above 6.7%. Density of the composites is cut down to 3.664 g/cm 3 and anti oxygenation of ultramarinen Fe particles in the composites is advanced obviously.
