Characterization and Evaluation of Property of Columbite–MgNb2O6 Synthesized by Chemical Route
Abstract A simple chemical route is used to successfully synthesized magnesium niobate (MgNb2O6: MN) nano ceramic material at various processing temperatures. The initial phase formation characterization has been studied by thermal analysis for pure MN formation using TG–DT analysis. The synthesized powder materials are characterized by X-ray diffraction (XRD), Raman spectra and energy dispersive X-ray (EDX). The formation of MN phase of powder samples is determined from the XRD. Average lattice constants of MN ceramic sample are measured from XRD data. The formation of MN phase of synthesized samples is also identified by Raman spectra. The chemistry is measured by EDX analysis. The photoluminescence spectra shows a broad blue emission band centered at 426 nm and the band gap energy is 2.19 eV as measured by UV–Vis spectroscopy using Tauc equation. The photoluminescence and optical property of synthesized MN ceramic material are studied at room temperature.
