Preparation of magnetic nanoparticles by one step synthesis with morphology of particles changed based on time of reaction and temperature treatment

摘要

In present study, nanosized iron oxides particles are synthetised by easy one step precipitation from Mohric salt (NH_(4))_(2)Fe(SO_(4))_(2)·6H_(2)O reacting with sodium hydroxide solution in temperature up to 60?°C. When changing the time of reaction, the iron oxide particles of different shape are prepared and when drying wet extracted particles at elevated temperature of 60?°C the change of 2D shaped morphology is observed. Depending on the time of reaction different ratios of FeOOH and Fe_(3)O_(4) are obtained in this study. DTA – TGA, XRD, FTIR and SEM are used for the characterisation of particles in this study.
