Abstract

Maghemite nanoparticles of 40 to 150 nm are obtained by the thermal decomposition of preliminarily cryochemically modified iron acetylacetonate. The composition and structure of the obtained particles and cryomodified precursor salt are determined by the X-ray diffraction (XRD) analysis, thermoanalytical methods (thermogravimetry, differential scanning calorimetry), infrared spectroscopy, and transmission electron microscopy.

低温化学改性乙酰丙酮铁（III）的热分解合成磁赤铁矿纳米颗粒

摘要

通过初步冷冻化学改性的乙酰丙酮铁的热分解获得40至150 nm的磁赤铁矿纳米颗粒。通过X射线衍射（XRD）分析，热分析方法（热重分析，差示扫描量热法），红外光谱法和透射电子显微镜法确定所获得的颗粒和冷冻改性的前体盐的组成和结构。
