The influence of high-energy ball milling of reactants on a heat activated synthesis of SrFeO2.5 from hematite and strontium carbonate was investigated by X-ray diffraction and thermogravimetric analysis. According to our study the temperature and time required for the reaction can be significantly lowered by ball milling of reactants. A wet mechanical processing of the mixture is the fastest way to reduce the size of reactants' grains and therefore bring the temperature down. Apart from this,...[Show more]
