The oxidative dissolution of cobalt oxalate and manganese oxalate in acetic acid solutions with a flow of oxygen–nitrogen mixing gas at pressure of 1.5 MPa was studied. Experiments investigating the following parameters: the stirring speed, the reaction temperature, the concentration of oxygen ...detailed
The microwave synthesis of MnC2O4·2H2O nanoparticles was performed through the thermal double decomposition of oxalic acid dihydrate (C2H2O4·2H2O) and Mn(OAc)2·4H2O solutions using a CATA-2R microwave reactor. Structural characterization was performed using X-ray diffraction (XRD), particle s...detailed
Rod-shaped nanostructures of manganese oxalate (MnC2O4) were synthesized via mild thermal precipitation and aging process. Chemical composition of the MnC2O4 nanorods was confirmed using Fourier transform infra-red (FTIR) spectroscopy and energy dispersive X-ray spectroscopy (EDS). X-ray diffrac...detailed
It is found that the known regular structures of MnC2O4·2H2O (I) do not allow to refine the powder X-ray pattern of (I) properly using the Rietveld method. Implementation of order-disorder scheme [28] via the including of appropriate displacement vector improves the refinement results. Also it ...detailed
