摘要

通过对铁(III)的甲酸盐和柠檬酸铵进行热分解，采用喷雾低温干燥法进行低温化学处理，得到了高度分散的各种形态的超顺磁性氧化铁粉末。通过x射线衍射分析、热分析方法(TG、DSC)、红外光谱、扫描电镜和氩热脱附测定比表面的色谱法等物理化学方法对所得颗粒和低温改性前驱体盐的组成和结构进行了表征。

Synthesis of Iron Oxide Nanoparticles by Thermal Decomposition of Cryochemically Modified Precursors

Highly dispersed powders of superparamagnetic iron oxides of various morphologies are obtained by the thermal decomposition of formate and ammonium citrate of iron(III), subjected to cryochemical treatment by the spray cryogenic drying method. The composition and structure of the obtained particles and cryo-modified precursor salts are characterized by the following physicochemical methods: X-ray diffraction analysis, thermoanalytical methods (TG, DSC), IR spectroscopy, scanning electron microscopy, and the chromatographic method for determining the specific surface by the thermal desorption of argon.
