Nanocrystalline transition metal oxides (NTMOs) have been successfully prepared by three different methods: novel quick precipitation method (Cr2O3 and Fe2O3); surfactant mediated method (CuO), and reduction of metal complexes with hydrazine as reducing agent (Mn2O3). The nano particles have been characterized by X-ray diffraction (XRD) which shows an average particle diameter of 35 – 54 nm. Their catalytic activity was measured in the thermal decomposition of ammonium perchlorate (AP). AP decomposition undergoes a two step process where the addition of metal oxide nanocrystals led to a shifting of the high temperature decomposition peak toward lower temperature. The kinetics of the thermal decomposition of AP and catalyzed AP has also been evaluated using model fitting and isoconversional method.read more

Particle Size Determination from X‐Ray Line Broadening
L. S. Birks,H. Friedman +1 more
TL;DR: The x-ray line broadening method of determining particle size was compared with direct measurement on electron micrographs as mentioned in this paper, and the results showed that the particle size could not be determined unless the two maxima of the distribution curve were completely resolved.
