Microstructural design of lead oxide–epoxy composites for radiation shielding purposes

摘要: Composite epoxy samples filled with PbO and Pb3O4 were fabricated to investigate the mass attenuation characteristics of composites X-rays in diagnostic imaging energy range. The effect density on ability for radiation shielding purposes was studied using a calibrated X-ray machine. Characterization microstructure properties synthesized performed synchrotron diffraction, optical microscopy, scanning electron micros-copy. results indicate that increased an increase density. particle size WO3 fillers has negligible value coefficient. Microstructural analyses have confirmed existence uniform dispersion within matrix average 1–5 μm filler loading ≤30 wt% 5–15 ≥50 wt%.
