超细Fe_3O_4粒子表面包覆酞菁钴性质研究

A Study on Properties of Surface of Ultrafine Particle Fe_3O_4 Wrapped by Phthalocynine Cobatlic

本文研究了合成载氧体的金属有机化学液相淀积法制造工艺，所得产物经ＴＥＭ、ＸＰＳ、Ｍｏｓｓ－ｂａｕｅｒ谱和Ｂ－Ｈ仪等手段，研究了它的结构和磁性能。实验表明，酞青钴以薄层形式包覆在Ｆｅ＿３Ｏ＿４的表面，封闭了Ｆｅ＿３Ｏ＿４的表面孔洞，稳定了Ｆｅ＿３Ｏ＿４的物相，增强了磁性能。

This paper studies the producing pro-cess of synthetic oxygen carriers with the method ofmetalloganic liquid deposition. The structure andmagnetic properties of the products are measured byTEM XPS Mossbauer.Theresults show that thephhJocyanine cobaltic(PC)covers the surface ofFe_3O_4 with it's thin layer,it seals the surface holesof Fe_3O_4,stabilizes the phase of Fe_3O_4 and increasesit's magnetic properties.
