Abstract : Different ratios of ZnO and MnCO3 were mixed and processed by ceramic route to investigate phase relations in the Zn-Mn-O system using differential thermal analysis and X-ray powder diffraction techniques. Except for Zn1-xMnxO we detected two different spinel phases in this system. FactSage program was used for the construction of the Zn-Mn-O phase diagram in air and oxygen atmosphere. To verify the composition in several parts of the diagram at the temperature of interest, a number of high-temperature annealings followed by quenching was performed. © 2014 Elsevier Ltd.
