Stacking Faults and Micro Structural Parameters in Nano Magnesium Oxide (MgO) Particles using Whole Pattern Fitting Technique.

Abstract

Nano-composites of Magnesium Oxide nanoparticles are synthesized by solution combustion method employing Sucrose as fuels with corresponding metal nitrates. The synthesized nano particles by solution combustion method were subjected to XRD and SEM analysis for the characterization process for estimating the size of crystalline particle and figure out the morphology. The as-prepared powders are all nano-sized (180-260 nm) and the same is confirmed by broadening of the X-ray diffraction peaks and Scanning electron microscopy. XRD results show that Crystallite area increases with increasing temperature. The crystallite size (<N>), lattice strain (g in %), stacking faults (αd) and twin faults (β) determined by whole powder pattern fitting technique, developed by us. We have studied the microcrystalline parameters from XRD. Activation energy has been computed for these systems
