Mössbauer effects and XRD analysis of the solid solution formed from mixtures of different metal oxides by 800°C activation
Abstract
The results of present work indicate that when the mixtures formed by adding K2O, Cr2O3, CuO and SiO2 to α-Fe2O3 in turn accumulatively were activated in air at 800°C for 5 hrs, different reactions between α-Fe2O3 and the added oxides were caused, and different compounds were produced, hence role of various oxides as promoters and supports could be understood further.
