Sintesis Nanopartikel Magnetit Dengan Metode Dekomposisi Termal

Abstract

Synthesis of Ferri oxide magnetite (Fe 3 O 4 4 ) has been developed in recent years. The superparamagnetic properties on magnetite nanoparticle were widely used in industrial application. Problem in the synthesis of metal oxide nanoparticles is agglomeration of nanoparticles whereas dispersion of nanoparticles as a necessary requirement in a variety of applications. Synthesis of magnetite nanoparticle by bottom-up method using thermal decomposition was carried out in this research. Then the magnetic nanoparticle was characterized by using SEM (Scanning Electron Microscope) and PSA (Particle Size Analyzer). Based on the analysis, the result concludes that the process of thermal decomposition of Fe (III) acetylacetonate up to 280 nanoparticle with varying size distribution. The diameter size of particle Fe 3 O have range from 50,0 nm to 53,9 nm. The number of distribution was 50,0 nm about 69,27% and mean of particle size was 51,3 nm.
