In this work, we characterize the hollow hematite (a-Fe2O3) micro spheres obtained by two non-template techniques: Sol gel and, spray roasting process. Both techniques allow the production of high yield hollow hematite spheres up to 100 g for the case of sol gel and up to 500 kg for the case of spray roaster process. |
