ferroferric oxide

Study on preparation of nano-sized carbon/ ferroferric oxide composite material

碳/四氧化三铁纳米复合材料合成研究

Ferroferric oxide was coated with silica by sol-gel method, and doped with dithizone. The modified nanoparticles were characterized by SEM, FT-IR and VSM.

合成了四氧化三铁颗粒，通过溶胶凝胶的方法负载二氧化硅涂层，同时进行双硫腙的掺杂，得到双硫腙修饰磁性纳米材料。

Decomposing zinc ferrite to zinc oxide and ferroferric oxide selectively under reduction atmosphere was proposed, and acid leaching and magnetic separation processes were carried out to separate zinc and iron from reduced zinc calcine according to their characteristic difference.

本研究拟在弱还原气氛下将锌焙砂中的铁酸锌选择性分解为氧化锌及四氧化三铁，依据二者理化性质的差异，采用弱酸浸出-磁选组合工艺实现铁锌的分离。
