Deskripsi
In present study, nanosized iron oxides particles are synthetised by easy one step precipitation from Mohric salt (NH4)2Fe(SO4)2·6H2O 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 Fe3O4 are obtained in this study. DTA – TGA, XRD, FTIR and SEM are used for the characterisation of particles in this study.
