Abstract:
This study presents an innovative approach utilizing gamma scattering techniques to precisely determine the composition percentage in a two-component oxide compound. The experiment involved a 241Am gamma-ray source emitting 59.54 keV radiation and a Si(Li) detector to capture Rayleigh and Compton scattering signals from oxide powder samples. These samples were meticulously prepared by blending Pb3O4 and ZnO, with Pb3O4 proportions ranging from 0% to 100%. To ensure accuracy, eleven standard samples were employed to generate standard curves for Rayleigh intensity, Compton intensity, and the Rayleigh-Compton ratio. The key finding of this research was the calculation of composition percentages for the four samples under investigation, derived from experimental data and the standard curve. Validation against reference materials revealed a minimal relative deviation of approximately 1.0% when estimating the Pb3O4 ratio, showcasing the precision and potential applicability of this method in material science and analysis.
