ABSTRACT: The as precursor, HMTA as fuel material and non-ionic surfactant (Triton-X 100). The X-Ray diffraction (XRD) analysis revealed that the synthesized ZnO nanopowder has the pure wurtzite structure. The ZnO powder shows polycrystalline nature having the crystallite size 21.25 nm. Crystallite size is calculated using Debye-Scherrer’s and Williamson-Hall equations. Porosity, Cell Volume, Micro strain, Morphology Index, Lorentz factor and Lorentz Polarization factor are also studied. From differential thermal analysis (DTA) & thermo gravimetric (TGA) it has been confirmed that nano powder has the phase purity. The weight loss percentage of the sample is 2.8385%. The particle size obtained 29 nm is in good agreement with the crystallite size calculated from X-Ray Diffraction pattern with the Particle Size Analyzer. The morphology of as prepared Zinc oxide nanopowders are characterized by scanning electron microscope (SEM). From specific area electron diffraction (SAED) pattern has specified the d-spacing and corresponding planes which coincide with the XRD d-spacing and planes.
