FT-IR and thermal studies of iron-nickel-manganese ternary levo-tartrate crystals

摘要

Several metallic tartrates deserve special attention due to their various applications. In the present investigation, mixed tartrate crystals of three different metals are reported. Using single diffusion gel growth technique, iron-nickel-manganese (Fe-Ni-Mn) ternary levo-tartrate compound crystals were grown with different concentrations. Spherulitic crystals with different coloration were obtained for various concentrations of metals. The concentrations of metals were determined by EDAX. The presence of functional groups was confirmed using Fourier transform infrared (FT-IR) spectroscopy. The powder XRD study suggested that the crystals belong to the orthorhombic system. The thermal stability of all the samples was studied from room temperature to 900 C. It was found that the composition of the crystal affects the dehydration and decomposition behaviors. The results are discussed.
