Abstract EN
Nanoparticles of calcium metaniobate compound are prepared by an autoigniting combustion technique and its structural, optical, and dielectric properties are investigated.
The X-ray diffraction, Fourier-transform Raman, and infrared studies reveal that calcium metaniobate possesses phase pure orthorhombic columbite structure with space group of Pbcn.
The average particle size of the as-prepared nanoparticles obtained from both the Scherrer formula and transmission electron microscopy is ~37 nm.
The optical band gap calculated from Tauc's Plot is 3.25 eV.
Photoluminescence studies reveal that Calcium metaniobate can be used as an idealphotoluminarmaterial.
The powders are pelletised and sintered at an optimized temperature of 1350∘C in a short duration of two hours, yielding a high density.
The morphology of the sintered pellet is further examined using scanning electron microscopy.
The dielectric constant and loss factor values measured at 5 MHz for a well-sintered Calcium metaniobate pellet are found to be 27.6 and 5.3×10−4 respectively, at room temperature.
