Transformation mechanism of magnetite nanoparticles [PDF]

Materials Science-Poland, 2015
Abstract A simple oxidation synthesis route was developed for producing magnetite nanoparticles with controlled size and morphology. Investigation of oxidation process of the produced magnetite nanoparticles (NP) was performed after synthesis under different temperatures. The phase transformation of synthetic magnetite nanoparticles into
