Description General description Zinc iron oxide nanoparticles are chemically stable and exhibit superparamagnetic properties. There are a number of methods to prepare ZnO nanoparticles, some of them are self-propagated combustion of fuels (alanine, glycine and proline), co-precipitation, sol-gel reaction, spin coating, ball milling and auto combustion. Application Potential applications of ZnFe2O4 are gas sensors, catalysts and MRI contrast agents. Packaging 10 g in glass bottle Legal Information Product of Engi-Mat Co.
