Abstract
Iron oxide particles were prepared by a simple organic precursor assisted thermal decomposition technique. Microwaves were used as a source of energy for both precursor synthesis and generation of heat required for thermal decomposition. Ferrous oxalate dehydrate prepared within the microwave-assisted solvothermal process possess needle-like particle morphology with the length of about 20µm and submicrometric diameter. Magnetic iron oxide was formed by a topotactic decomposition of prepared precursor in a microwave reactor thus the final product also preserves needle-like shape and possesses soft ferrimagnetic behavior.
