AN EFFECT OF BALL MILLING ON MICROSTRUCTURAL PARAMETERS OF NANOSTRUCTURED MoO3-CuO-V2O5 COMPOSITE NANOPOWDERS

The present work meant to look at the impact of crystalline size, lattice strain and dislocation density of ultrafine thermally excelledMoO3, MoO3-CuO and MoO3-V2O5 composite nanopowders utilizing mechanochemical milling process at various time interims. The characterization of the nanocomposite synthesized powers was characterized by a range of spectroscopic features such as Powder X-Ray diffraction, Scanning Electron Microscope and Electron Dispersive X - Ray Spectroscopy. With the X - Ray peak profile demonstration, the orthorhombic phase of MoO3, V2O5 and monoclinic phase of CuO were shown. On the basis of XRD, Deby - Scherrer and W - H calculations the average crystalline size, lattice strain and dislocation density evaluated were almost equal. SEM images of MoO3, MoO3 - CuO confirm that the irregular shaped particle sizes and MoO3 - V2O5 displays the spherical structures irregularly shaped and deposited with vanadium flakes. The presence of constituent elements of prepared samples is confirmed by EDS spectrum.
